Maybe this is a dumb question!
I'm just wandering is there any way/web part integrating with SharePoint, by which I can communicate with others instantly.
The reason behind this requirement is that I still have not found any workaround to communicate with my colleagues instantly, like MSN, in SharePoint.
P.s If I start building one, where should I get started!
Thanks for your input and forgive me if my question is stupid!
Check out chatterbox: http://blogs.msdn.com/sharepoint/archive/2007/05/15/chatterbox-persistent-chat-session-for-sharepoint.aspx
You can integrate Microsoft Office Communcations Server into SharePoint apparently. Gives you access to MSN Messenger internally to your enterprise, among other things.
Users who run Windows Live Messenger will get a precense icon for all user lookups when their email settings are configured properly. It requires all users to add each other to their live accounts, so it might not be the solution you are looking for. Another way to get the precense icon is by using Microsoft Office Communications Server as Moo suggested.
This also integrates well into Outlook and is the way Microsoft decided to implement communication in the Office suit.
chatterbox works great except you cant see who you're talking too unless you know your teammate is on the same page. otherwise better used as a comment system.
