Hi Vanessa,

Thank you for your nice words :)

The way you dynamically get files is extremely interesting but, there is 
catch,
for the moment I prefer to serve a few medium sized files than a lot of 
little ones.
The server is very little and I use it to do a lot of stuff.

I will keep this option in my mind, in due moment I will ask you more 
detail.

It would be expecially important for the directory "CoreUpdates" where 
there
are a LOT of files and usually only the last of them are useful (to me).

In my opinion running a Smalltalk in the Web has huge potential, at least
for business intralan web applications where dev. time is important and
fading pictures and other eye catcher are not so relevant.


bye
Nicola
