Instant notifications by IM
 

vbulletin added email notifications in a time when everyone was using email. Now Instant Messengers like MSN* Yahoo* Google Talk* AIM* etc are used much more than email.

Please update notifications to make them instant notifications by IM. Allow:
New PMs by IM* notifications of subscribed threads* groups* blogs* VM* friend requests* friends coming online notifications* etc.

Competitors have it... vb should as well.
