Welcome Tankless,
I am a member of THR, but it's too "high" traffic. I couldn't keep up with all the posts. Alas, when DRTV grows to big, I'll have to figure a way to limit what I read.
Don't put it off, competitive shooting, just jump in somewhere and get a taste of it. GSSF Indoor League, if you own (or can rent) a Glock, is a simple competition to start. Don't let all the rules of IPDA slow you down from entering. It did me and I'm sorry I waited so long. In local matches weekly indoor matches most clubs are pretty flexible. As long as you're safe and have safe equipment they'll let you shoot. Of course, you may get some penalty points, but that's okay. It's the experience that counts.
