That "try again later" message was not sent by the people at Mudcat. The site designers surely would have chosen better wording if they had any control over that.

I don't know where the message comes from -- maybe it's from your own browser -- but you get the same message regardless of what web site you're trying to access, if the web site doesn't respond within a certain amount of time. By "respond" I mean, send a message back to your computer. Even though it hasn't sent the message, it may have done lots of other things, like update the thread.

We have a bunch of people called JoeClones who have the power to delete messages. If they happen to notice a string of duplicates, they will delete all but one. It happens all the time.
