I've tried asking many people what I put in the catchall domain in the Tube Booster software, and no one helps. I've contacted the Tube Booster maker, and he doesn't answer. I need to use this program asap to make accounts, so please help out. So what do I put in the catchall domain? How do I set it up? I don't understand how I simply can't use a gmail account and have all the accounts forwarded there, so the software can then verify the youtube accounts made? Please help.
