Tina, I missed the original thread but I see Malcolm Douglas gave the same reccomendation as me - it really is the best starting point. Also you may like to check outhttp://www.mudcat.org/thread.CFM?threadID=19529 which is pretty compact and lists some of the other favourites.

Another reccomendation I have is to read the Mudcat FAQ (the perma thread at the top of the list of threads as it gives info on the searching this forum that Malcolm mentioned above and plenty of other useful information for getting the most out of Mudcat.
