Ok the scoop on the guild. It cost 10 silver to get a charter. We need 10 unique players. So I am taking that as 1 real person’s account and not including alts.
Then it costs 10gold for the guild tabard design. I am thinking blue design on a white tabard. Maybe red on white. I think they will look sharp. Then it costs 90 silver per tabard. I guess we will try the “Knights of Druidia” as our first choice.
Our Characters have to be in the same proximity in order to sign the charter. So we will have to travel and be together to do this. Joy! 
One tactic we can employ if we are short is to get a noob to sign the charter and we bribe him with money or goodies. He can then choose to stay in or leave after the guild is formed.
I think the first 98 slots in the guild bank are free. Then we have to pay extra gold to unlock each of 5 more 98 slot banks. If its like regular bank then it goes 10g then 25 gold +++ etc. so everyone save up.
