Sorry about the duplication, I realized shortly after this post that it fit better in the marketplace topics. As for the selling, I am not acting as a middleman, but I collect books and every so often decide I don't actually want or need them, and thus sell them on ebay. I suppose I never thought about proving that I am not selling them as stolen, as there are so many millions of people selling things on ebay with no proof - but for the record, I am not selling them illegally, and I have purchased them all. I do not do this as a job, but more as a hobby, a few sales a month type of thing. But I will check out Telegram, thank you. I thought Telegram was merely a messaging app, didn't realize one could create "channels" there.
