If you've "passed" on a project I offered you or dropped out at the last minute due to "unforeseen" circumstances, please don't send me your NOT so funny emails saying stuff like this:
1). I have this great project we should work on.
2). We should work together since we never got the chance.
3). Dude! I love what you're doing. I would love to work (aka hop on the bandwagon) with you now.
Or anything related to the above!
