I Upgraded to 1.2.6... thanks for your work!
I would to suggest a little option...
In the summary page or in the dashboard (if a user is logged):
He can see the users online!!
I saw it in the dashboard of friend blog with splinder.
He can see the list of gravatar (avatar) of the users online and send with them private messages!
I know You are already working at the private messages.. so.. It would be interesting to have also the list of people online in this moment..
It's only my mind.
Thanks more for your work.
