I have created a tag board for my site. Well, it will be more correct if I say I added a tag board, because I didnt create it myself, but I am using a free service by cbox. It is very easy to set it up and it looks pretty cool too. The basic service is free, but if you want premium service you can pay them a nominal sum of $2 to get a tagboard which is ad-free, has archiving capability, online counter, banning etc etc.
Let me see if anyone is putting up any comments in my tagboard
