I have the project of potentially hosting an NWGFL (and Movement knows it because we talked about it) but not before September as I feel it will be impossible to have a serious commitment from teams during summer vacations and the biggest issue with these sort of leagues is often commitment. If people actually want it to happen sooner then I suppose you can look into it Smylie. I wouldn't recommend it, but at the end of the day, it's your tournament, your schedule.
If nothing happens, then we can talk about it again in September. You don't need many teams to run NWGFL, you just need them to complete the full event in order to make it successful and that's often what proves the hardest thing to do from a host point of view.
