Welcome to the sci-math-moderated newsgroup, a newly created, lightly moderated math forum on Google Groups based on an open format unlike any other moderated math forums.

Join up now, post your ideas or questions on any mathematical theme or volunteer to be a co-moderator. Open ended questions, new ideas and extended discussion on any mathematical topic are to be encouraged. Moderation is intended only to prevent trolling and abusive language.

All can visit and read. Only members may post here, but once your membership request is approved by a moderator (a simple process), your postings will usually not require any further moderation.
