I think when you look at your own profile and go to posts

there should be something there to let u know that someone else has replied or just posted something after you....that way when you post something somewhere u wont forget to check it later on.

it would make it a hell of a lot easier to check the threads that you are talking in, instead of searching around trying to find all of the threads that you have posted in

also maybe make it so you can see all of the threads you have posted in that week? instead of the latest 5?

just some ideas...
