WARNING: This repo is NOT the official factions repo.
It is an internal fork, not used (or updated) in years.
The current official repo is @drtshock/Factions.
Please go there.
You may have wound up here from google search. This is a mistake. I was never a primary developer of factions, I was only a contributor for a short time.
I still get some emails about this, especially asking for a free copy. This was allowed for small and non-profit servers. AFAIK, that policy is still in place, but you should not ask here.
If you have any issues, or questions, or just anything, please go to the official repo at @drtshock/Factions.
Last I checked, the spigot page is https://www.spigotmc.org/resources/factionsuuid.1035/ and the maintainer was https://github.com/mbaxter. This may change over time, so you should verify this.
In the future, this repo may be deleted or made private. Don't rely on its existence.
