I have installed 'newLatex' as a package (in a local library directory) for Maple 11.02, and made a few tests, comparing the output of 'latex' and 'Latex'.

latex(x^2 + y^2 = z^2);
{x}^{2}+{y}^{2}={z}^{2}

Latex(x^2 + y^2 = z^2);
Error, (in newLatex:-LatexString) Sorry, at present _Inert_EQUATION cannot be translated to LaTeX

Latex(x^2 + y^2);
x^{2}+y^{2}

latex(Int(1/(x^2+1), x));
\int \! \left( {x}^{2}+1 \right) ^{-1}{dx}

Latex(Int(1/(x^2+1), x));
Int \left( \frac{1}{x^{2}+1},x \right)

Here, if output is to be converted it should be "\int" instead of "Int" and "dx" be used instead of "x" as second argument.

I have also compared the dvi output for the matrix 'expr' above. The differences that I observe are in minor details: that of 'Latex' is slightly narrower and uses upright "i" for the imaginary unit.

Perhaps you could show some examples with marked differences?

I would say. A plot:
F:=int( ln(2+2*cos(t)^2+cos(t)^4), t );
plot([Re(F),Im(F)],t = 0 .. Pi);
shows that this imaginary part is the imaginary part of a piecewise "integration" constant.
F:=int( ln(2+2*cos(t)^2+cos(t)^4), t );
plot(Re(F),t = 0 .. Pi);

If you see discontinuities like here do not use blindly the definite integral. If there were a Maple wiki, this should be in the FAQ.

So, it should be just a matter of uncheck those that are not of interest.  But  for me , the  problem is just the  opposite:  I have never received  any notiffication  since   August 2005, though Will then said that I should receive them. And now, eg I have  this thread subscribed and yet I am not receiving any notiffication (the same holds for another subscribed thread with this feature present).

I am observing the syntax highlighting of Maple source using the Cream variety of Vim for a file with extension .mpl. Apparently, there is no builtin direct mechanism for injecting this code into Maple or for calling Maple to execute it, but  you have to cut & paste or communicate via a file.

(Manuals > Browse manuals with info) I see that the location/classification for the Maplev mode and some other math modes  is a bit strange:

Maxima
* Maxima: (maxima).            A computer algebra system.

Math
* Giac : (giac_us).            Computer Algebra System Library
* Giac en castellano: (giac_es).    Programa de calculo simbolico por
                    Bernard Parisse

Math
* GNUPLOT: (gnuplot).            An Interactive Plotting Program

General Commands
* Bzip2: (bzip2).            A program and library for data
                    compression.

....

* Mtools: (mtools).            Mtools: utilities to access DOS disks
                    in Unix.
* Maplev: (maplev).            MapleV, a GNU Emacs major mode for
                    developing code for Maple V, a
                    computer algebra system (CAS) produced
                    by Waterloo Maple Inc.

So that you should made a little search before finding the entry for Maplev.

In My account > Subscriptions > threads, I see in this moment 19 entries (4 blog and 15 forum), corresponding to threads to which I have posted. Some of them are quite old, but this one is included.

Clearly, these are a fraction of the threads to which I have posted. My guess is that this list will enlarge as the scanning of the database continues. Is it right?

On the other hand, I have not received yet an email notification of Will's last post here. I think that I should.

In My account > Subscriptions > categories , the last section is "Userpoints". What is that?

So, I will try it (even though I find Emacs' design barely tolerable). How do you configure it to use different versions of Maple? May be that you add some notes to your blog post?

By the way, I cannot distinguish any Maple code against the black backgound of those screenshots.
