Tapatalk is a forum manager, something not existing in a desktop environment as far as i know. there is a tapatalk add-on for chrome though.
I suggest to visits tapatalk websito to know how it works. The thing is that with tapatalk is much much much easier to use forums. It's one the things that work so much better in tablet/smartphones than computers. It will help this site to have more frequent users, more users and have a much more active forums. Also i think it consumes much less bandwith for the server of this forum.
You need to try it to know how awesome it is... also, lot of people used to tapatalk tend to use less and less those forums not supported. And anyways, it's not difficult to implement it. Just update the phpbbforum version of this website and solved...
