I have been reading threads here for about a month before I joined. I never once posted as Guest, not because I thought I would have bad treatment, more to find out about the place and get a feel for it. I think I did the right thing. The argument for privacy etc. does not work, you can call yourself "paperclip" if you want - no person will know who you are. I think you have dug a bit of a hole for yourself "Guest" Unless this was the intention - just to stir up the forum. I give you the benefit of the doubt.
I use my own name as I feel quite safe here
