Jeanette - thanks for offering! I will definitely be looking for some help soon. So far I'm still figuring out how things will best be organized, but in the not too distant future I would like to have moderators focused on a particular topic they are knowledgeable about/interested in..so be thinking about that.
Karen - to add a signature or change your avatar, there is a "personal settings" link near the top of the page (just under the logo and "Sew What's Up"). There are tabs to manage different aspects -- what you are looking for is under "profile." Let me know if find what you need there.
