You might not really want to do that ...publish your contact info to the web.So any ideas on how to do it??.
I have no problem with posting my phone # and email.
You might consider starting a private Yahoo group or similar. You can password it and use the PM function on this forum to forward the password to known members. It is not totally fool proof but much better that publishing phone numbers in the wild. Plus the little effort required will demonstrate at least a mild commitment to the goal.
