Thanks for all the replies.
I really dont give a hoot about the congregational aspect of the card being kept. As some of you have said, it's just a card. I could care less what the org. thinks of me.
The reason why this concerns me is the gossip that attaches itself with it on a social level. I would much prefer being in a situation where ppl say, so-and so moved to a different cong and assume that I am still in good standing than having them say so-and so is inactive. You know that this type of gossip floats around. Eventually this will come around to family members living in different locations who think you are active as well. It can get really complicated. I would like to maintain contact on a social level with all the ppl I know without the stigma. I have no problem with them. It's the org that I have a problem with.
I think I'll keep the card as is until they decide to call. That's when I may use some of your suggesstions. Thanks.
