in fact WG does all these region flags and more: pvp, mob damage, mob spawning, creeper explosion, ghast fireball, sleep disable, TNT, flint and steal, fire spread, lava fire, lightning, chest protection, water flow, lva flow, button/door use, vehicle placement, snow fall, leaf decay, greeting message, farewell message, administrator notifications on enter/leave, automated healing, blocked/allowed commands, respawn location, physical entry or exit blocking
I HATE ANTIGRIEFS XD i have dedicated MANY hours to creating the VERY best griefing plugins just look at Boom! over @bukkitDev
the only problem is that the WG group entry flags just relate to WG like the owner of a reigon or a member i need something that ties in with both WG's protection flag and PEX grouping
