Hi guys! I need help. I am having problems logging in. When I go to this forum it says I am logged in and everything...but...when i try to reply to a post such as my fanfic "Sister of the Prophets" the system says I am not logged in..so...I enter my info and then it keeps saying that! Can someone please help me clear this up??

The only thing I can think of is browser cookies. Maybe check to see if you're allowing them? Or just try restarting the machine.

Then how are you posting here? You could try just clearing your cookies entirely. Sometimes that works for me.
