But unless they tell that person back, they are stuck out of the convo.
You might #tell Ozzy, Pecker, Lastwish
Where I would #tell eViL, Pecker
Mainly because I don't know who you are talking to, That is unless it said who you sent it to.
It is still too much of a pain in the ass to keep up with.
Just use #group, and keep the people you want to talk to on it..
A nice idea would to actually clear everyone's group list everytime they disconnect.
