Can you provide some specific details - what operating system and browser are you using? Exactly what happens when you try to do this? Exactly when did you attempt to do this?
Yes, lets ask loads of questions and then not give a resolution.
Perhaps if you read the other posts on this forum about registration issues you'd realise that it isn't just one person having a problem and that something is actually wrong.
I can understand your frustration but there's no need to be snappy. Firstly, I'm not part of the support team; secondly, staff can't always instantly respond to a thread - there aren't support members constantly on the forum, looking to aid people (as it's not the official support section).
Thirdly, one simply cannot offer specific help without specific details - all the OP has stated is that he/she cannot submit. Well, other people have and quite a lot of them too:
Over 8000 projects were submitted in the last 24 hours, so it's clearly not a global issue. As in all cases where there is a problem, full details have to be submitted to see if there any patterns or known unresolved cases.
