I stand corrected, he didn't like that there is no application process.
For anyone else interested in the world - you don't have to jump through hoops to get into NABCL - I do my own research.
I click on your profile, look at your current teams, look at your team history, look at your length of stay in worlds, the quality of those worlds, the parity of those worlds, your records ("tank" seasons are definitely a red flag), etc.
I then look at the world chat in your current worlds, your trade history, your team names, etc.
If I determine that you are a good fit after completing my research, you get the password. If I have questions on anything that I feel needs to be clarified, I'll sitemail you the questions.
NABCL is a very good HBD world, and I am a very attentive and detailed Commissioner.
