Guild Hall and GvG Questions!

Sorry if this is a repeat, but I just had a couple questions. I'm actually just tryin to settle some discrepencies in my guild.
I'm the Leader of the guild WotW Warriors of the Wind, my in game name is Trent Longbow.
We just got our hall on Thursday, so we're kinda new to the whole thing.

Question 1:I had heard that in order to have a GvG battle there had to be at least 1 officer present per team, is that true? Because I just came back from vacationing to find out that over the weekend, there were 2 battles, and my other 3 officers, all said that they weren't there. So, I want to find out if either one of them are lying or did I just misunderstand the actual rule and fail to tell the guild, the right thing.

Question 2:I had also heard that the higher your guild rating or better the guild rank, you will actually start getting npc's in your hall, like maybe a community vault to change objects, and/or just adding other stuff in the hall, I would just like to know the truth on that, and if there is a chart, a link to it.

Thanks
Trent

For question 1 all guild members can start a guild battle until the next patch. For question 2 I'm not 100% sure but I think the answer is no.

So at the next update, only officers can start the battles? Oh and another question, sorry. You can't have 2 Guild Leaders can you? Me and another guy are co leaders, but i'm the leader, just becuuase in presearing i had 100 gold befor ehe did. I just want to make him the leader with me.
Thanks
Trent
