I was interested in trying this, but the UI is like pulling teeth. I couldn't accept the ToS because the checkbox was under the terms box, and had to tap very carefully.

Then I tried to create a Hub, but couldn't figure out how to get it to accept my drawing (there's no "done" button, only "cancel", even though the polygon I want is right there). After a few frustrating tries, I went back and noticed that I need to click the first point again, which is very unintuitive.

After that, it kept complaining that my area is too big, and there was no way to live-adjust the area while seeing how big it is. I had to cancel out of the whole thing, go out to the hub screen, then click "start drawing" again for another try. I didn't make it past that.

Thanks for the feedback! I increased the max size from 125 hectares to 5000 hectares. I had some debate about what would be a good max size, not so large that it takes up a whole city, but also not so small that few people can join it. For some reason which I can no longer remember I landed on 125 hectares.

It is probably too small, but for now I just want to make it easy to use. At the default zoom level 125 hectares is tiny and I am not surprised it was hard to make something small enough. I just got so used to the way it worked when I was testing I would immediately zoom in without noticing.

It will not save your hub unless you're logged in. The logic was that since someone needed to be an admin, they needed to be logged in. I should probably find a work around for that for now while I am just trying to get people to test it out. No one wants to give their email to some random site.

I am going to work on making the hub drawing more intuitive. It should really have a done button.

Thanks for giving it a try.
