I posted a message about 15mins after the last I had posted, but I get a message saying I have posted within 5seconds - I can't type that fast!!! Is there a bug with this board? (Pun intended.)

Yes.

Seriously, it's coming up for DST changeover. Expect freakiness.

I'm not aware of any post limits bugs - I've posted about five times in the last twenty odd minutes myself. Let me look around the XMB forum for boards suffering similar bugs and I'll get back to you.

I've had the same thing happen to me but not recently. It can be frustrating.
