double post

Not sure if this is an ongoing issue, and it's fairly minor at that - but wanted to fire this into the ether.

Posted in a thread (and I noticed a previous double post in the thread), but after I clicked the "post reply" button once, an error came up and said "you have to wait 30 seconds before posting again" and had the whole thread in a single page, written on top of itself over and over. (Looked like a bunch of gobbledegook.) I knew there was a previous double post, so instead of reclicking the post reply, I went back and saw my thread had posted correctly. So anyway, not a big deal, just wanted to let you know what happened and why folks might be double-posting.
