The stamp idea is a good one. Like I've said in previous posts on this topic, we don't get a lot of people coming to our meetings with "slips" to sign so it hasn't become an issue. I think we all agree that our anonymity should be protected regardless of the requests made by outside sources. By signing my initials, I'm not being dishonest...but I'm also not revealing anything more than I'm comfortable with. I will not give my phone number to some unknown entity and my group doesn't own the facility where our meeting is held - so it isn't my place to give out the facility's number as a contact. IMO, requesting too much info is overstepping a boundary and we shouldn't be held (directly or indirectly) responsible.
