You can also earn oil in daily missions and Clan Battles as described in their details. Other containers, like the Yamamoto, October Revolution and other purchased containers also earn 10 oil apiece. If you let the game collect the containers for you, you will not earn oil at this time. Currently, for your three daily containers (2k, 12.5k and 37k) you MUST collect manually to earn oil.

Oil is earned from collecting (not opening) containers. Players can send an application to a Clan from the Clan page in game by typing in the Clan tag and then sending the application. You can also reach the player profile from the main WoWs page by searching on a player name to get the same Invite to Clan button. Right clicking from there allows you to access that person's profile and if they are not in a clan, there will be an Invite to Clan button to send the player an invite. You can send invites in the game by opening a chat window with a player in the port. There are plans for a Builder office for using oil to make the buildings, but it is not active yet. The wiki says that Recruiters can remove players, but the Recruiters in my clan don't have the exclude button to do that. There is a Recruiter office and that person can invite and accept players, but doesn't have any other authority. You can change yourself from Commander and assign that to someone else, but then that person has all the authority (Delegate button is not reversible unless that other person Delegates the clan back to you). You can designate Deputy Commanders who have the same access (the Modify position button). The Cmdr can make the buildings and do all of the other functions that are added. The Clan Commander has the authority to invite and remove players.

In case you haven't seen the info about clans in the Team Play forum, I can give you some basics. I assume there is something besides Dalia explaining it

The only thing I could find was in WOWT and said #5 was right to disband clan, and everyone but recruits had it.

Inviting, Rights distribution, resource access. I thought I could figure it out, but I have many questions.
