If you haven't already I would suggest you join Defiant Events channel. There you will have the best chance to get or set up a team.
Plus there are regular ITF and LGTF runs that are advertised on the Events channel.
Happy to be on Defiant.

Ok, How do i join the Defiant events channel? Is it done via a command ingame?
If you right click on your chat window, you can bring up a menu so you can channel search.

/chanjoin, Defiant Events
saves a bit of time 
If anyone's online right now who is 45+ and fancy making a team please contact my character Grey Jackal. I've been at 47 for god knows how long now and there is never anyone on to team up with.
Or, If thats not possible could someone please tell me the best way to get to 50? I'm having to solo alot of missions at the hardest difficulty and i can't help wondering if theres something more that would help.
Just would like to someday reach 50 for my 1st really active character
