i just installed uddeIM to test it...and see if i will use it on my site.....

anyways, is it possible to add the auto-complete feature for names (or usernames)...

Actually there is no autocomplete feature. This feature is on my todo list now.

You could use the "connections" feature instead which shows a combo box with all connections a user have.

alright. sounds good.
i have another feature request thou.... which is more important to me than the name autocomplete...

i want the messages to be threaded...all msgs between the users on one page (if you have facebook then u'll know what i mean )

"autocomplete" is available in the trunk now.
