Newbies should be able to join a guild on their own.
The move to put the guild joining to primarily be just for the players has led to the demise of the guilds. Combining organizations just so that activity is centralized is a flawed logic which has contributed to the decline of the game.
As it is, guilds that are dying or dead cannot grow mechanically or from within. It only takes a couple of players to go dormant for an organization that has been built/nurtured for years to go dormant as well, and eventually be shuttered off.
