Re: Deleting personal messages
If you click on the "0 new messages" text in the top bar, you'll see your messages centre.
Click on 'Sent messages' in the left hand menu (about half way down)
Now you'll see a list of sent messages. Click the tick box to the right of each message you want deleting - or goto the bottom of the page and click 'Mark all' to select them all.
Just under the last message on the right is a pull down menu the current says 'Marl/Unmark as important' - click on this and select 'Delete Marked' - and click go.
BTW - for everyone - I'll up the message storage limit so your inbox can hold more messages!
