Faction White list for access

Its a tricky thing to ask someone to trust everything they own to a stranger and allow them to join a faction. In multiplayer most of us want to branch out and make new friends. However we have all been burned by letting a new member into a faction only to have them steal everything in sight as soon as everyone else is offline for the night or just bounce around to all the faction med bays and then share the coords publicly to everyone on the server. Right now the only option is to leave you stuff on private or share it with the entire faction. There are a couple ways to solve this.

1) Make a whitelist options for the access to the medbays at the very least so that the creator can set access to certain members of the faction without setting for anyone in the faction. This way a faction can allow access to new members to some of its bases and ships without necessarily giving a new member the ability to access and potentially destroy everything they have worked for.

2) If a white list is too much trouble at least set up a ranking system with say 3 or 4 ranks that can be granted to members of a faction. Then give the option to grant access to med bays to the various ranks of members. So rank 1 would allow anyone to spawn. Rank 2 would allow ranks 1 and 1 to spawn, so on and so forth.

3) On a similar note access issues have been caused by the collaboration of multiple people building a single vessels as no one owns all the blocks. Make it so that a faction leader has the permission to claim and or reassign the ownership of all blocks so long as all the blocks are owned by any faction member. As it is everyone who worked on it has to access the control panel and change ownership of all the blocks they own to nobody and then someone claim it. Its unnecessarily complicated.
