Yes I am seeing the bottom of the page. The delete button isn't there or anywhere from what I can tell. Where the hell is your button anyway? Can you post a screen shot or something?
I pulled the following from the FAQ. Are you saying it no longer works like the FAQ says it does?
How do I work with 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. It allows you to view all the messages you have received, along with the name of the person who sent it, and the date and time it 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 for future reference.
You can 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. Once you have selected your messages, you can choose the following options in the 'Selected Messages' box at the bottom of the list:
Move to Folder
Delete
Mark as Read
Mark as Unread
Download as XML
Download as CSV
Download as TEXT
You will need to periodically delete old messages, as the administrator has probably set a limit to the number of private messages you can have in your folders. If you exceed this number, you will not be able to send or receive new messages until you delete some old ones.
If you would like to keep a record of your messages before you delete them, you can use any of the 'Download as..' options listed above to take a copy and store them on your own computer.
Whenever you read a message, you will have the option to reply or forward it to another member of the forum. You may also have the ability to forward that message to multiple members of your contact list.
