Keeping in touch

I think it would be great to be able to keep in touch with everyone, but I have found in the past that this is difficult. It seems every time you leave a job or someone moves away that the intentions are to stay in touch but usually it doesn't happen. Life changes take place and other things seem to take the time that you would otherwise use to keep in touch. But, I do agree with Perry, an E-mail list would be a good idea.
