Yep, If you go to your Inbox you will see on the right hand side of the screen a checkbox beside each message and beside each day or week. You can select a message or a day/weeks worth or indeed all the messages in your inbox. Once you have selected all the ones you want to get rid of scroll to the bottom of the screen and you will see a 'Selected Messages' box, if you click on that it will give you options as to what you can do with the messages you've selected. pick the one you want & hit 'Proceed'.
You can do the same with 'Sent Items' and clear your outbox if you have one. Once cleared you'll be able to receive PM's once again. Cheers Dave

Noted, but please assist me with instructions for "clear your PM log". It does seem very intuitive for me.

Willi can you clear your PM log, no one can send you a message - but I needed to send this:

Hi Willi,
Love your Macchi M.5, however, the painting showcase is for pictures of the end result of your labours rather than the how to of it.
The boss's intention was to have a reference of images with a brief explanation of colours decals used with a link to a thread where the full detail is shown. Initially he wanted no comments in the the showcase at all - it was impossible to stop those but we can try to cut down the comments to the barest.
So, in future can you post a thread in the Hobby Room and only a pic or two in the showcase, this will cut the comments down as questions & answers about technique, colours, materials etc will be done in the Hobby Room.
Advantages are the Hobby room attracts a greater audience so the info is shared more widely; it ups your thread and post count & you're likely to pick up more REP points for your work.
This is the reason your Rumpler thread was moved, if you can post a thread in the showcase along the lines suggested above with a link to the Hobby Room thread I will ensure that is entered as an official painting thread as there is no Rumpler C.IV thread.
Thanks in advance for your co-operation.

Cheers Dave
