Well i thought you're allowed to use your sessions however you want. Be it lending one to a friend or w.e. doesnt matter.
Actually selling it is not forbidden, it is forbiden to sell it here.
But also be aware that i run into few solf Gatherbuddy Accounts and the new owners got scammed. As they can not prove to me that they paid the original invoice and that the payment email adress is theirs - i can not just give them the account, so the previous owner gets it back by email reset for example.
So you can even sell it, but do it with persons you know where they live![]()
