No idea how useful this will be to anyone else, but rbthma mentioned that in the 145 league he has to manually remove every member from the teams page whenever the league restarts. which is frequently. and very time consuming!
I wrote (poorly) a simple script to automate this process, feel free to do with it what you will. if it is used by more than one person I will consider making it into a browser extension
go to the team page for your league eg: https://fumbbl.com/p/group?op=view&group=3180&p=teams
if using chrome press F12 and go to the console tab
paste the following code in (https://pastebin.com/6RWh098g
) and press enter
wait some time..... it doesnt auto refresh so maybe open up the page in another tab to check if all teams have been removed yet
likely this isnt useful to anyone else. but figured would share just in case!
