I know that the "your post has gone into moderation" message goes by fairly quickly, so I'm not too surprised at this.
Yes, that's an understatement! I had to hit the back button to read it. But if I wasn't watching the screen (something I sometimes don't do) I would have been one of the folks doing multiple posts. (Or at least sending you some private emails. ).
If you could increase the timeout it might save you some grief as you get more of your other Thoughts Forum members to sign up.
BTW: As an aside: So far I really like your new forum software. I haven't tried it on a Pocket PC yet. Does it work there too?
