please check your profile for a valid mailadress, I have been receiving lots of mails from my mail delivery system that mailadresses aren't valid. I don't want you to miss a valuable e-mail sent by another member
Note: hotmail.com and other free mailaccounts drop your account if you don't use it for a certain period. Better to have a good and stable mailadress than those free accounts!
Now check out your profile @ profile,mode,editprofile.html
