Well, I don't like to have my inbox receive the number of emails on a
list like this. The new interface is a much better way in my view.
I already receive 100+ emails every day so doubling this seems not to
be a good way for me....

I have seen you mention "echo" a number of times and I have gone back
(in the Gmane gmane.comp.compilers.free-pascal.general news archive in
my newsreader) to locate the exact method for this but I failed.
And I am a total noob in this low level handling of Linux...
I will continue searching for your echo examples after I return home
