Topic: Supported IM Screen Name(s)
Currently, PunBB supports Jabber, ICQ, MSN Messenger, AOL IM and Yahoo! Messenger.
My first request is that MSN Messenger should be changed to 'Windows Live Messenger' as this is what it is now called.
Secondly, in all my time using PunBB (this may just be a coincidence ...) I have never ever seen the Jabber field occupied. Perhaps it could be replaced with something more popular? Skype, for instance.
Support for one's favourite IRC network and channel could also be implemented (though that is probably more suited to an extension).
An alternate solution would be to allow users to add any screen name for any client that they so wish. Though having this sort of free-form data like this (as was described to me the other day) is not suited to searching at all. (Unless the search is changed somewhat.)
