Thanks all. I tried logging out, and back in. Still says "Your inbox is full!"
I don't want to renew my Platinum membership, because I am moving soon, and have sold/given away most of my flocks, and have hardly anything for sale. Therefore, hardly getting any PM's, and not doing any auctions. Don't need the extra storage space for photos, saving my $$ for now. When I get up and running again, I will be sure to renew. Mostly this time I got the Platinum membership just to support BYC. I don't think my PM account should be held hostage just because I did a one time support measure to BYC. HELP! lol.
