This is not a new idea, but I couldn't find the discussion or idea using search..lol.
Yes, Guild should be able to select the type of guild they want. So, what type of guilds exist?....
The friends and/or family guilds that want to limit players to just that... friends and/or family.
The solo guilds where players just want to enjoy the game in peace all by themselves.
The top guilds that pretty much like to keep their Guilds to invited players only.
The casual guilds that play for fun and welcome all players to join.
It's a shame to see players having to post... don't join... join by invite only... etc. and messages on the Guild page like... I've already kicked 4 players, join and you'll be the next.
Sure would be nice if guilds had an option of selecting... Open, Invite Only, Solo.
If and when implemented, a symbol on the Guild page showing the guild type might be helpful.
