eBay seems to have similar logic. I've never understood why I can't delete messages from my "Trash". :D

Vbulletin is the best s/w for forums that we could find. It isn't perfect. I am still working on moving PMs to different folders....

Here is their blurb on it...

Private Message Folders

By default, you will have two folders in your private message area. These are the Inbox and the Sent Items folders.

The Inbox folder contains any new messages you receive, and allows you to view all the messages you have received, along with the name of the person who sent the message to you, and the date and time the message was sent.

The Sent Items folder contains a copy of any messages that you have sent, where you have specified that you wish to keep a copy of the message for future reference.

You may create additional folders for your messages by clicking the 'Edit Folders' link.

Each folder has a set of message controls which allow you to select messages, then either move them to one of your custom folders, or delete them completely. You may also have a button which allows you to forward multiple messages from a folder to another member of the forum.

You will need to periodically delete old messages, as there is a limit to the number of private messages you can have in your folders. If you exceed the number of messages, you will not be able to send or receive new messages until you delete some old messages.

Whenever you read a message, you will have the option to reply to the message, or forward that message to another member of the forum. You may also have the ability to forward that message to multiple members of your buddy list.

I'll agree with you 100% on that. :)
