OT too quick to post two posts

[fc_miller]

Just tried to reply to a message in quick succession, and got this warning

"This forum requires that you wait 30 seconds between posts. Please try again in 1 seconds."

How long have we had this feature?

Pretty much forever I think.
I've had the same message a couple of times.

Since the dawn of time.

James bond style though as I got the message with '1 seconds' left...
