theymos is admin and in theory you can PM him.
I am however sure he gets - a lot - of PMs and I am pretty sure he will not reply to all.
Generally if you have a question about bitcointalk or whatever you can also just ask it here.
* also this topic should be in forum "Meta", I think you can move it with the link "Move Topic" on the bottom left. But I also reported it so a moderator could move it.
