I don't think registration should be required...I tend to skip over the "controversial" stuff that has especially been causing the problem as of late...I like the fact that when I go back to New York from California, I can access Mudcat via my sister's computer (or any computer, for that matter, to see what's been happening). The Guest feature is a good new addition...
Like with TV channel surfing, if you don't like the particular thread, skip over it!
Glad to be a Mudcatter!
