WorldGuard flags help!

Hello-

I run a server with a spawn area protected by a WorldGuard region. No non ops can build or destroy anything in this area. They can open doors, however. We have some small apartments in the spawn area that can be rented by the players for a weekly fee. I am trying to set up a region-within-a-region to allow players to build and use furnaces, crafting tables, chests, etc in their apartment. I tried making a new region with me as an owner but cannot seem to have anyone else be able to access the furnace. I have tried setting the flags use, passthrough, build, and construct, but none seem to work. I don't want to use addowner if I don't have to, as I don't know which player will be renting that specific apartment. All I get is, "You don't have permission for that in this area." Is addowner the only way to unlock the region for that specific person? Can anyone who has a bit more knowledge with WorldGuard and its region function help me out? It would be greatly appreciated.

Thanks,

So you want any player on the server to be able to use that furnace but not modify the region?

 

Yes and I want them also to open chests, use crafting tables, and sleep in beds.

 

/region flag <id> chest-access allow

 

I tried that but it only worked for the chests, not for the furnaces or crafting tables.

Can anyone else help?

addmember

 

Will doing addmember enable them to destroy blocks? Because I want them not to be able to destroy or build to prevent spawn griefing
