Hmm maybe someone will be able to help you here, but, if not, perhaps just contact support and ask them directly. I have the highest level, and I'm not sure that I can organize any live tournaments (I think I can organize a turn-based tournament through a group, but I've never tried that).
Here are some potentially helpful posts, although I realize that they are not related to organizing the tournaments yourself:
- Membership Levels (you can play unlimited tournaments with the platinum level)
- Membership & Online (Turn-Based) Tournaments
- Live Tournaments (at the bottom it confirms that the unlimited tournaments applies to live ones as well)
Making me Premium can I do play tournaments where only people I choose? If so, what level of premium should I choose?
