Newbie: Problems with File IO

If you want to remember them forever (sic) then use cookies.
http://www.python.org/doc/current/lib/module-Cookie.html

If you want to remember them from post to post during the same "session"
then use a session object (a temporary cookie in effect) or encode a
unique session into the url (not as easy).

pyweblib.session contains all the functions you need.

Then you would simply

User connects
Do they have a session?
No - generate one.
Do they have a username?
No - ask for it and store in session username
and
Call the clean up function periodically to clear out old sessions.
On your page display the session username.

Remember to use try: or has_key or else you will get errors if there is
no username key in the session object.

For pyweblib see http://www.stroeder.com/pylib/PyWebLib/

Documentation isn't a strong point but the library should give you a
help.


Hope this helps

Thanx! That's got me a bit further. What part of the standard Python
manual 
(the html one you get at Python.org) would that be under?

Also, if you could give me a hint as to how I might get the script to 
remember people's usernames everytime they post, that'd be good.
