(thanks to supersat for hosting it :))
If someone has any arguments against having it committed (or can think of a better wording than 'Y! Nick' ('Yahoo! SN'?), 'MSN Address', and 'Jabber Address') please let me know... I'll send it to Brad if there's no complains or bugs... :P
Oh, yeah... and I added Jabber while I was at it... :)
Update: It's now 'Yahoo! ID', 'MSN Username', and 'Jabber', to comply/stay consistent with what is asked for/shown at the userinfo-page.
