Sometimes, I like to review parts of a thread, so I don't use that in my preferences. So many pictures that need to be looked at again, and so many comments that were skimmed over....not to mention going back to check spelling of names in the midst of typing them. I love the way Dave has this site set up! We're having a couple of issues at the moment, but he will get it fixed. In any case, it's only one click to first unread. Try Orchid Species. com sometime, and you'll find out about mouse cramp!
