I had this request again and again: "Where can I find a forum for GLM users?". Unfortunately, I didn't have any answer for a while...
I decided to contact the OpenGL.org website webmaster James Riordon to ask if I could redirect GLM users to the OpenGL Toolkits forum and I get an approval for this idea.
I also want to recall that GLM have a bug tracker which is the best way to summit a bug, even if I receive most of them by email... From now, I will redirect developers to the bug tracker to accept a bug request.
