By the way, I am seing this formula perfect in text form using Elinks, a text browser.

It could be another workaround...

No, I do not have any experience with MapleNet or knowledge about it besides reading the page at the Maplesoft site.

My understanding arises from "black box" observations under change of  options in  my  browsers.  And thinking how I could implement the site myself.

Eg right click on the image menu has also the option "Block images from mapleoracle.ma...". Select, reload the page and there is no formula image.

On the other hand, software producing images from formulas to be included in html, use to label the image files with the text of the formulas and/or use them in the alternate text field, to be used with non graphical browsers. This is used  on the server side eg in Wikipedia.

And it seems a usual configuration to have a separated image server. Some browsers (eg Firefox in some versions) have an option kind of  "allow to receive images form a different server". 

Time ago I have unchecked  it  (thinking that it was safer and it would help avoiding pop-ups and other spam nuisances) and soon forgot completelly about this as everything seemed to go well. But one day I have realized that the math in the Wikipedia articles was not being nicely typeset as it used to be (LaTeX like source code was shown instead). After some time I got tired of this situation and I  decided to ask for help at a Wikipedia help forum. The advice received was pretty useless: empty the cache, turn off/on firefox, delete I do not remember what, reinstall firefox (obvioulsly it should be completelly corrupted, even when I claimed that I was observing the same problem both on Windows and in two other Linuxes, etc, etc). Soon I got tired of those advices, and shortly after I have  realized that the solution was pretty simple: check that option. It was not in any FAQ.

Some links point to the newly redish styled "student forum", where I get this order of the right column blocks:

"Announcements", "Recent blog posts", "Active forum topics", and  "Recent comments",

instead of the order elsewhere:

"Announcements", "Recent comments", "Active forum topics", and "Recent blog posts".

I find this change a bit inconvenient. Is it possible to get, while in this "student forum" the same order as elsewhere?

Also, as this stylistic distinction was made, instead of the bluish style elsewere, what about labeling with a redish bullet, or something like that,  the  links  that  point to this forum?

While reading the old documentation it has always intrigued me the phrase:

The system kernel is written in macros which can be translated by a
locally-developed processor (called Margay) into versions of the kernel in the
C programming language.

Ie. why locally-developed and why that strange name.

Well, with currently available Google or Wikipedia, it turned out easy to see that it is a kind of cat. So, presumably, it was named after this animal. It seems that this animal lives from southern US to northern Argentina,  it is given different names in different countries and, most curiously,  "Margay"  is precisely  the name  given in Argentina, but over a thousand kilometers north from here.

So, who could have given such a name to that macro processor?

By the way, shouldn't a macro processor make things easier?

Also, I observe that the duplication remains several minutes after I have closed the other two browsers, and after several refreshes of the page.

Now I have my account opened from tree browsers: Firefox, Opera and IE (opened in this order), and I see my username twice. Why not three times?

A pair of hours ago, or so, Primes suddenly "went to maintanance" and I went to lunch. Now I see this thread. I have never set the option "Who's Online", so I cannot explain much.

Could it be because I had my account opened from two different browsers (in the same PC) at the same time?  (to compare how Primes fares in each of them).

Later, I will set on this option and try that again.

In "Account settings" > "Private message settings" there is an option (I think new):
"Aggressive notification of new messages".

Though it sounds a bit "frightening", I have checked it, but I wonder what it means.

May be related to the absence of the number between brackets in "Navigation" > "My inbox".

With the same setting (Firefox 2.0.0.11 under Windows XP) the toolbar is OK for me.
However, with Opera 9.25 (also Win XP), this blog page is upset: the editor has no toolbar, the "Input format" block appears in the right column, and the blocks that should be on the right colum appears at the bottom, on the left colum (apparently the same occurs with every other page except "Home").

This is better for me. Thank you.

Anyway, I do not get  "Recent Files" yet.

I have set:

Main_Forums, Student_Forums and Collaborative Books, unchecked

Recent blog posts, Active forum topics, Recent comments and Recent Files, checked

(the rest unchecked)

And I see:

Announcements, Active forum topics, Recent blog posts, Recent book pages and Recent comments.

So, eg. I do not understand why I see "Recent book pages" and not "Recent Files"

Also, if I cannot  reorder blocks, could you put "Recent comments" higher?
