Just remember...you have to be logged into the forums to post from a computer. It is a different login point than just being logged in to RR. Does it show you're logged in at the very top of your screen? And does ur show you're logged in just above the forums on the right hand side? I had the same problem when I first signed up not realizing I had to be signed in to the forums separately from RR.
I am logged in at the top. I am not logged in at the right side in the forum page. U have entered my info and then clicked the link to reset my password. I then went to email and followed the link back. I'm still not logged in. I attempted to log in and now it says I have exceeded my log in attempts.
