This is called in French "réanimation" or resuscitation
of an old thread that interests me in particular since, upon joining this fine group of "stampers", I have given a lot of stamps, all over the world, to people I felt were - beginners - and over time, I changed my method, giving to only people-members with 50 posts or more. I give the stamps, pay for shipping, and 50% of the time, will receive an acknowledgement from the recipient member.
The last member request was for Luxembourg dups and this a.m. some 50-60 older stamps left for the Southern US (Florida). I am eager to see if I will ever get a "thanks".
In summary, you try to pick the people who will benefit the most but......no control.......Internet and this Community is a large pot pourri of people........just a thought
