Hey Zgamerman I was involved with a really long running POL server.
It has a lot of features which make it easy to customise with years of work from amazing people made a great role play server. However unless you are a pretty good coder or know one, I am not sure its the platform to start on with a project.
Very few people willing/able to code in E-script. Those who could easily learn can find most needed guidance at
https://www.polserver.com/
You might get lucky and find someone here who has past experience. However the majority of the forum would find it incredibly different to servuo.
Sadly I am not very talented on the code front, so I cannot offer much or any real help with the deeper customisation of POL.
I suppose this is not much help, but unless you have got a POL based shard that is 90% complete or in some other way amazing.
I am not sure I would start using it now over:
RUNUO (defunct or not a lot of resources still exist)
ServUO more aimed to emulation of vanilla UO but with a growing and active community.
With that said, POL community maybe really busy these days, I have been out of touch for a long time. However if your set on POL then their community would be the place to seek proper help.
