Ok, sorry if this questions has been asked a thousand times already, but I have to do it again.
I googled it and the anwsers of that were, ask pretty much anyone and you'll have dozens of members in no time (2013 I thought was anwsered)
So, here I am, trying to get some members in the guild. Problem is... it's not working
So in Haven I'm not sending random invites, but ask first politely, to be ignored 90% of the time and decline the other 9,9% by the guildless members.
In the arcade I sometimes ask too, if it was fun to play with the person that is.
