wikispace now supports math

see <http://blog.wikispaces.com/2007/05/math-in-wikispaces.html> for
details

The wiki in question is <http://xenharmonic.wikispaces.com>, though
you are certainly free to make another one if you have different aims.
There might be a need to counterbalance the fleeting nature of a
mailing list (though less so since Yahoo's search has improved) with
the need to generate a stable (yet dynamic) database of content.

Gosh knows that wiki needs some increased participation if it ever
hopes to get off the ground... This is an ongoing invitation, of
course. (If you were waiting to fully jump on board because of the
math display limitations, your day has arrived!)
