Had a problem earlier today in posting a reply to a thread. Wrote it up, then clicked "preview post". It looked okay, then I clicked "Add Reply". The server said that I had to wait 45 or more seconds before posting again. Seems it though that I had submitted the post to the forum and didn't let me submit it again (to avoid duplicate posts, which is reasonable). The software seems to confuse "preview" with "add" with respect to this restriction. I did check the thread, and my post did not appear, so that would rule out "preview" being taken a "add reply" by the eserver.
