Just checked your profile, there is nothing wrong. The simple reason for the restrictions is, that you were not logged in. As a guest you can only read the postings and download files, nothing more.
If you don't want to log in every time you visit our forums, check the box for the auto log in during the log in procedure. Your informations will be saved in a cookie on your drive and the forum software will recognize you when you come back.
Please have a look in the FAQ section, there are very good descriptions how you can add files or pictures to your postings. But like Peter said before, the filesize is limited.
