- I recommend for this Core Protect it's useful to rollback and log and inspect log of grief, doors, chests, it can roll back nearly everything, it can roll back world edits also, damage caused by mobs or players, nuke or any other kind of bomb.
Yes, factions is the best protection I found, dark matter and red matter wont harm your spawn, or the people playing. believe it or not, it's most stable.
-LWC of course it locks chest, doors, furnace and other stuff as you want on tekkit.
-it have most common stuff like /tpa, /warp, /weather, /me and more useful commands.
- Essentials group manager plugin
don't you want admins and mods, or special permissions for each user if you want?
olor your chat depend on user rule, it's compatible with the above and ready to go, unless you wanna change colors to different ones or have a special chat format.
- World Edit
Useful copy paste, fill, replace, build mass projects and pimp your spawn with this tool, it's essential if you wanna work good and quickly. don't worry it have an undo command.
