You don't want to give up your 1122 posts.
It doesn’t matter how good my new community might be. You’ve invested a lot of time to collect 1122 posts. It gives you a VIP status.
If my community lost the first-mover game, I'd start an exchange rate.
Your 1000 posts can buy you a VIP star badge on your profile at my community. Or you can get special products from my client. Or you can have first-look and unique feedback opportunities.
Or anything that makes it easy, fun and worthwhile to trade and transfer your status to my community. Try it.
