Hi Syed, It's been a while since I looked for any ... but if it's just a question or two now and then, why not try "thechat"? I know we've got some astronomy and advanced (abstract) math folks over there that might welcome an interesting technical non-web discussion now and then. HTH, RonL. (Who's advanced abstract math skills are probably pretty darn rusty these days.) -----Original Message----- From: Syed Zeeshan Haider [mailto:szh at hotpop.com] I don't think this question is very ON-TOPIC. But with a tip after it, here it goes: Evolt is a list for enhancing and developing web technologies. Right! Are there other lists, with systems like Evolt, which could deal with other fields of science like Physics and (Advance) Mathematics. Please tell me about any good lists about these two subjects, if you know any.
