Is there any way to save private messages that you want to keep so not to fill up your in box. Thanks P.M.

If you go to your private message control panel, create a folder, then move your messages there. I don't know if this folder will flag to others that your PM is full but you may want to try it. If I received tons of PM then I would know. Keep in mind that if this does work and if everyone saved there PMs then JohnR would need more hard drive space.
You could always save to a folder on your computer the index of your PMs and each individual PM.

Thanks for the info I 'll do that . P.M.
