Hi MTeegardin
Yes! Every constructive feedback is very welcome

I think you already discovered a jOpenSim repository in GitHub. Stay tuned, content will follow there soon

I lately get help from jjandtkalt who will dig into the last issues concerning PHP8 and xmlrpc and I hope we will be able to fill this repository with a J4 ready version in quite near future.
We both have a RL to "struggle" with, so I better dont promise any specific date

but be sure we try our best to get jOpenSim back on track for Joomla4/5 and PHP8 as soon as possible
