Finding other transpeople is easy... I used Craigslist personals and met a few good people that way. But other options are good as well.
But meeting with them safely for the first time is a problem... How do you know you're not inviting a maniac with a gun? How the other person knows you aren't that maniac? One transgirl showed at my door with a gun in her pocket, btw... so it's not just a wild stipulation.
I suggest meeting in a public place, trans friendly, or just any public place where both of you are comfortable to be. Then, proceeding or not further.
