Hey Andre. I'm sorry to hear about this trouble with the message boards, and I'd like to help.

I checked the message board in Football, both with IE9 and Firefox 13.0, but couldn't verify the issue that you are referencing. Each time I was allowed to post a message, and regardless of how long I waited, it worked each time.

Typically, this means that the issue would be specific to your browser.  I would recommend starting with How to clear your browser's cache and cookies.

Also, some features do not working in older, outdated browser versions. I would check your browser version, and verify that it is current.

If your browser is current, and clearing the cache and cookies doesn't work, please let me know. Also, include the browser name, and version number, that way I can continue to attempt to replicate this issue.
