Starting an alumni chapter?

[Kevin]

There's probably a great deal of experience on this subject here. I had a few questions in mind. First some background:

I and a few of my fellow alumni/chapter founders want to start an alumni chapter. That is a chapter of alums from a specific chapter. Those of you that are a member of one of these, what types of interactions do you have with the active chapter? How much/how often? What type of assistance do you offer them? What do you do on your own?

Also any additional info that ya'll could offer me about 'how things should be done' would be helpful.

Thanks!
