Tapatalk is has two sides.. server side and client side.
I installed the client side here.. it allows anyone with the tapatalk client to view the forum from their android device, iphone, ipad, blackberry, etc...
The format is easy enough - i'll use it at night sometimes.. though being at a computer gives you the full effect of the site.
There are a ton of forums out there that use it - I think its $1.99 for any of the supported phones.. find it at the apple app store, android market.. whereever blackberry ppl get their stuff.
