Avleen Bijral, one of the students here at TTIC, sent me a link to a pretty cool browser plugin for GMail called GMail TeX. Basically it lets you send LaTeX formatted emails via gmail. This can be quite a time saver for the reader (but maybe not the writer) if you’re remotely collaborating on some project (which I so often am these days, it seems). It’s supported on a wide variety of browsers and seems worth checking out!
