Tapatalk - I think you can find extension on Tapatalk's website.
Show Poll Voter Username - you can try Advanced Polls Extension
(though I'm not sure if it has all the features).
User Blog Mod - This one isn't converted to extension. I'm not 100% sure, but I don't think author of this MOD is active here.
Attendance Mod - I don't know this one, but it seems that someone is working on hookup extension
. Maybe it has similar features.
