So you're selling something in that group, right? I have a group with about 140,000 members in the US, but the topics are quite general, and I don't know how to make a decent amount of money given the group's size. Could you help me out? We could share the profits, or if you have other offers, let's discuss them.
The group really does have interaction between members, and between the administrator (me) and the members. I don't know if you've experienced the same thing, but I frequently have to log into the admin page and reply to their messages. And that's just the admin page; I get a lot of messages in my personal account. I've already posted a notice stating that I only handle issues on the admin page and won't address private messages.
Honestly, I don't want to sell the group, but I'm currently facing financial difficulties because a family member is sick and needs money for treatment, so I have to find a solution. The fact that you joined that group three years ago when it had just over 20,000 members and then grew it to 140,000 without engaging in blackhat activities shows, to some extent, that you've taken the group seriously and cared deeply about its growth.
