My message box is always overflowing

, and I do delete quite a few, so was wondering if, when a person gets over 1000 post, they could be entitled to, say 250 - 300 messages??

I would think that 80% of members rarely use this feature anyway?? Perhaps less than 1000 posters could be entitled to 100??
I have many messages that I dont want to delete - things I have purchased, messages of support, humour and general newsy stuff of interest from the wonderful guys/gals here.
