hmmmm....it works...but needs refining like all the IM plugins do....

This plugin seems to add your Facebook contacts to your address book, but only those online at the time?

It also reproduces every IM under the same name if you close the conversation, once it restarts....thats a big bug.
If you keep the conversation open, it does not duplicate IMs.

I notice all IM plugins have a little failure at the mo to allow a user to remove/delete contacts if desired, without them coming back again.

The MSN plugin even imports blocked contacts into the address book, which just reappear if you delete them.

This is progress...but it needs lots of work yet.
