I apologize if you feel this way, we weren't planning on releasing the Thinker group for money until at least 100+ members, but mis-communication caused this. I don't believe we are that money hungry, we give a free upgrade at 200 posts, and the upgrade that costs money is $5. On other sites it is $15-$18. As for Groups, I need it to be an amount that people will prove people will be focused on their group, if it was $10 or less, a ton of people would just propose mediocre groups because it was so cheap. We aren't asking/demanding any money, we're offering other accessories that you can use, for a fairly low price. Do note that at this moment, all of the costs of the site are coming out of our pocket, we need to make enough money to keep this place afloat.
Edit:
If you wish us to remove the Thinker usergroup and return the money, and remove the ability to have groups, then we can do so.
