An Unseated Player who is non-Wounded and non-Yellow may join a Gang by posting a comment to that effect to its Gang Post, however comments by any Player who is Wounded or Yellow or Seated at the time that the Train Robbery attempt commences will be disregarded and such Players are not deemed to be part of that Gang.

If this rule passes and a train robbery is in progress and seated players are included, they shall continue the robbery as if they were unseated. (this way it wont throw the robbery out of the loop by suddenly have the wrong number of players.)
