I think this would become a great command or they could add the option like groups where you can do /group add [Player 1] [Player 2] [Player 3] But instead it would be /vouch [Player 1] [Player 2] [Player 3]
Lets say i do /invitenear and 20 people join, i dont know their users, so it would be a pain to do /vouch player1 player2 etc, so that is why im suggesting /vouch group
Something like this already exists: /gr blockbreak. This allows all group members to break each others blocks. The main difference between a vouch and this setting is that it will remain active for as long as the group exists (or untill the leader changes it or someone leaves the group (then it will no longer apply to them)). The other option does more or less the same, but its effects are more permanent: /gr buildmode. This will ensure that every protected block placed by members of the group will be owned / breakable by all members of the group. Even if the group gets disbanded. Note: players would still need to ensure applying protection themselves. So they need to place umcommon blocks or use /buildmode (or both). If I read your suggestion right then these two options already cover all this.
People currently in a group with you will automatically be able to break your blocks EDIT: Ninja'd by Shel
That is not true, unless you do /gr blockbreak or vouch each person individually(which takes time) The blockbreak one is inconvenient cause many times the leader of groups changes or logsout, so everytime that happens the command would have to be typed in for buildmode, it would give the other players ownership which we dont really want. Is better to have segmented power, so in case a griefer somehow gets vouch from 1 player, it wont be able to grief all blocks, and only part of it. Also, /vouch group, would act as EquableHook mentioned. IT would vouch all players in group, but instead of /vouching 20 players which takes about 15s to do per player, It would be only 1 command
No, that's not the case. The setting retains for as long as the group exists or until it gets toggled again by the group leader. So quite frankly I don't see the difference between this or group vouch where intended functionality is concerned. Another concern I have with group vouching is that a vouch normally lasts for 30 minutes. With /gr blockbreak you have instant control over the member(s) permissions: the very moment they leave the group they also lose those permissions. With vouching not so much, which could get tricky if you're using larger groups.
Im inexperienced with /gr blockbreak myself, so i based of my response on what you said, but didnt get it quite right I read "or untill the leader changes it" without the "it", so that was my confusion
