Pretty sure you will need a plan but if you vote daily for 1 month you can gather enough credits to get the MH20 plan, which I assume would have all if not most of the important features to help servers that are starting out.
I just had a thought, how would custom plugins work? Obviously they would have to go under review so that they couldn't cause massive lag or have any malicious intent, right?
Alright I got to admit, this is very cool. Custom Plugins, Custom Versions, Live Console and most importantly; Server Networks.
