You're post count has been reset. That usually happens when people post every 5 to 10 minutes just so they can get 10 posts in a hurry.
Instead of trying to only post in the OT section, try and make meanful and useful posts elsewhere on the site. This can be achieved by either helping other users, asking questions, posting useful comments, etc. Please stop posting just for the purpose of getting in 10 posts.

XDA Developers was founded by developers, for developers. It is now a valuable resource for people who want to make the most of their mobile devices, from customizing the look and feel to adding new functionality. Are you a developer?
