Okay guys, I have created three H2H leagues (9 leagues were created in about 30 seconds!), feel free to join any one.
See spoiler.
As soon as 20 teams are in a division, I will close it. I will add the codes to the OP.
After 19 weeks, I will create a new division with the top 3 in each league, to run alongside the three divisions above. Also, the top 6 in each league + 2 others will be entered into the top 20 for next season.
Note: if you have already entered the H2H, you will not be in a league, so please re-enter. I tried to restrict the initial league to 20 teams, but it didn't do anything so I had no choice.
