Recently active topics in Mobog tagged with search engine

These are the things I'd love to see on mobog:

1.) A list of the people who have subscribed to you.
2.) A search engine, where you can search for a user's name or even photo tags.
3.) Threaded comments.

Otherwise, I really like mobog, and it's been a good fix for those of us who were users of orfay/yafro. Keep up the good work!
