Give Team Leaders an LFT Flag in the Search
I agree that a feature to flag team-leaders as being 'leaders of a team', it would solve the issue of people asking if they can join a team, only to get the wrong person.
A number of flags whilst in a team could be as follows;
Looking for members: The team version of looking for anything, useful for marking a player as the Leader of a team and to let others know that there is a team looking for people, so they'll think "Oh, instead of waiting around to be picked, I can ask this guy without worrying I'll be interrupting something"
Looking for <task> members: The team version of patrol, TF/SF, Arena, Missions...etc, a more complex version which helps leaders show up as people who will accept members for a specific type. This will be especially useful for those trying to gather up TF/SF teams.
Not Seeking: The same as before, but purposefully masks the leader's position as perhaps they're already full or they don't want any more team-members because they're just close friends wanting to play with each other only.
By adding any of these flags to team-leaders will help out team-gathering very much. It'll relieve some of the stress from leaders sending tells (or blind-invites for those who are naughty) and let other people come to them instead!

Instead of having the same gray circle as everyone else, the leader of a team should have a special flag, such that you can search for them in the Search interface.
Auto-assigning this would help a lot and is probably the easiest option. If you want to go one step further, let the team leader have two or more flags, such that he can say a bit more about his level of interest (Recruiting for TF, Open Radio Team, Not Inviting, etc.). Another step might be not assigning this flag to the leader of a Task Force or Ouro team once it gets rolling, since he obviously can't invite, but I don't know if that would be hard to code.
Adding another layer of search functionality by assigning a different flag to people who are on teams but not the leader would also be nice, because then we could filter them out.
