Ho knows why bitcointalk always make me wait 360 seconds before posting a new message? Is it because of their site engine??? And often after 360 seconds when I'm trying to make the post again it places a sign: "You already submitted this post! You might have accidently double clicked, or tried to refresh." WTF?
No, this is not because of the "site engine" of course
I've also met such problems when just registered here. I think it is a way to protect forums from newbies, who want just to flood or to make some fake messages. After you spent a few hours online (4 hours I suppose) you will have an opportunity to write messages every minute or so. So just be patient 
Good news
I thought this problem will appear every time I will want to write something!Yeah I thought the same))
