I believe that for most online people this is the first, most urgent, issue. The article I wrote on What to do when he/she leaves? is far and away the most sought out. It has been the top read article every month for over five years. I like its success.
While it seems to come first, I really thought you would benefit more from having the Lizard material under your belt. I think you will see this when in the papers I mention Panic - read Lizard. I open the topic now because it just seems to flow from AntigoneRisen's note on Topic 1: Friend your Lizard(s).
I believe that here is the whole problem of Abandonment and its solutions.
For this topic I want you to have the background of several articles. They're not as long as the Lizard paper. They are all articles on the Skills of Reliable Membership.
The second paper I suggest you look at is a more indepth look at the problem. It is called The Testicle Principle, and when you've read it you may see why I prefer talking to online people rather than your partners at home.
Curiously I haven't found any writings by anyone else about this topic. I am still looking.
Read away and come back with your observations, ideas, examples.
Principles are simple. Applying them is a tough U-Do-It project. Go 4 it! Al Turtle
