Check out this new website. It about anything maths based. If you need help with homework want to get an insight into a llevel maths want to solve a new problem or maybe you just wana chat and get involved with like minded people. Check it out

planetmaths-home

I would suggest that this site change its name as PlanetMath was there
first (not identical names but sufficiently alike to course confusion), as
was PlanetMaths.
