It seems that i can't reply to forum topics, i can only create new topics. Reading the messages here, it seems everyone has the same problem.
Welcome aboard John. I can reply, but you are right, it still seems to be wrong for some people. Avinash is getting it fixed as soon as possible!
It seems to be fixed now.
I (still) can't reply to forum topics (using the 'Add new comment' link). Only the 'Reply' link on other peoples posts work for me.
Thanks Anders for pointing this out. I have added this to the list for the web development team.
