Anyone have a good way to write equations over IM?

I often help friends of mine over IM with math stuff, but it's often difficult when you cant lay out equations properly.

I'm on Linux and using Pidgin as my IM client if anyone has anything client specific, although it has to be cross-client, as everyone else I know uses MSN messenger (or whatever they're calling it these days). There is a plugin for pidgin that supports LaTeX, but it just renders the LaTeX and sends it as a text string, so my friends on MSN just get gibberish (well, near enough to their eyes).

Any suggestions?

### Re: Math and instant messaging

Are you/your friends in a situation such that they can visit websites while chatting? If so, you could use CodeCogs. Eg:

http://www.codecogs.com/eq.latex?\int_{-\infty }^{\infty }e^{-x^{2}}\;dx=\sqrt{\pi}

(I apologize for the weird linkage, just copy/paste the entire URL to see how it works. I couldn't get the link to work properly on this forum with or without the url tags)

Just replace my LaTeX code with your own, and send them URLs.

There is also the facebook latex app: http://apps.facebook.com/mathematics/, although that works in messages and wall posts rather than IM.
