I'm convinced that, at any given time, there are hundreds (perhaps thousands) of English-speaking students looking for real-time chat-based math help for free.
My question: how do I find them and help them for free?
More info: every so often, I get bored and feel like spending an hour or so helping people with math online. Sites like openstudy.com sort of allow me to do this, but don't have a good real-time chat interface, so communication is ugly.
openstudy.com also discourages people from giving students external links (eg, I can help you at my scribblar.com whiteboard at ... ).
Is there a good solution here?
