I usually cut the pop-ups off before they get the chance to load though. What if the other users does the same?
This.
And what if they have AdBlock so it doesn't come up at all?
Maybe a better idea would be a warning at the top of the page, just above the editing box in red letters, something along the lines of "Warning: Once your thread has been made, only a Moderator can delete it!"
I think part of the confusion about deleting threads comes from the fact that you
can delete a thread, only
IF it hasn't had any replies yet, by deleting the opening post. If you do so however, you'll get an automated message from Momoka confirming that fact, but the message makes out like it was deleted by a Moderator as some sort of punishment for wrongdoing.
