What other list are there?

Hi, I am getting ready to start another project that will have to do a lot of math. So I need to ask some question on how to get php and mysql to do that. So can you tell what mailing list there because I think that I might have to ask other list since this is general list, I am I think this might be a little more advance. Hey, if I am wrong sorry, just thing to make sure a head of time. Thanks, Chuck Payne Magi Design and Support
