There is an in-game tool that many of you do not use and may not know about. Flag yourself as looking for a team! Many Redpills were doing this early after launch and it is how many of us met and stayed in contact for so long.
To do this, simply click your cell phone (button on right side of compass). Select team, then seek. Voila! You are now flagged as looking for a team! There is also the find option that will allow you to look for other players who have flagged themselves.
Advanced find allows you to look for players at specific levels and organizations as well as their discipline.
I have been flagging myself from time to time and sadly, I'm the only one who seems to be flagged. This is a very useful tool and we all should be using it from time to time! I encourage you all to get back at it!
