Used stamps exchanges.

I have just received an address of a member who hasn't been online since end of July. I have sent this member a message if I should send stamps, and if he will register the envelope. He has sent 2 envelopes and received 2 envelopes. No answer received. i will have this one expire, and will send if I see action on his profile. Could inactive accounts be avoided in the selection of addresses?

If you check the envelopes sent by that member you can see that the last envelope sent was at the end of July and was registered a few days ago. Two months later. And you received the address soon after it was registered.

So it seems that this member sent a envelope and didn't come back until the envelope arrived at the destination about two months later. If I got the correct member it seems it logged in yesterday.

Some members are less active. Some envelopes are mailed later or they get registered later. So a long time of absence doesn't mean that your envelope wont get registered.

But it's a good idea to check if you are in doubt.
