it took 58 posts but we got there in the end, the problem was it wasnt iterating over the last page which just so happened to be where the target userId was
in terms of an application centre, what do you mean? like where do the players apply? You’ll need to have them join the group beforehand but it should be possible, maybe if u used like a google docs form you could have a google apps script script which will take the results of that and send an API request to Roblox to rank them, not sure what the payment quotas are for google apps script but im pretty sure its free as long as u have low traffic
if they apply in ur game u will need to host a script on some kind of server but its definitely doable
