I sent you a PM.
I don't like to post my URL in public. In fact I removed it from my profile. I am paranoid. I think this is where those Russians spammers come and get vb url then bombard your forums. :-)

Thanks!
I already did some testing. I believe most of the bugs i found (until now) have already been mentioned:

- Folder-delete = Database error-message

- Mail sent via forum arrives two times at my mail-client (mail-header seems to contain duplicate entries of "to" and "subject")

- I tried to sent a second mail to check the above error, but i got the "Sorry, you can only send one message every 1 minutes."-message, even after currently ten minutes.

Floodcheck. Someone else reported it. I am currently looking at it. I can't duplicate it with a regular user, but did find something worth investigating.

That folder delete, I am detemine to squash it today.

Can you PM me a copy of mail received?

Did you try sending an email to your forum address to test the cron?

Done.
If you need anything else, just ask.

Yes, and it worked as far as i can see.

I believe floodcheck has been solved.
Another problem I spotted: Quotas. If you empty your sent item folder, quotas is reset at a negative value.

Some interesting info in the email you received. It carries the xmailer info from filburt forum

got the delete folder bug out of the way. Now, let's hunt for the double email.

Quota is behaving ok now.

HTML email has been possible all along. The advanced editor must be used instead of standard editor.

So I am not considering this as a bug. On my site I will simply add additional instructions for end users.

Wow, great job. Looking forward to this.
