There have been multiple times I've thought about recruiting friends to WGT to get myself some free balls, but I stop every time.
Why? Because it's e-mail only. What's the deal with that WGT? Most sites that have a recruit thing will have it so you can just link them, so it's like wgt.com/ref=282958235 or w/e each user's referral code is. Why doesn't WGT have this? Other than the fact that people don't use email near as much anymore socially, it's just a pain. "Wanna join WGT?" "What's that?" "A golf site, give me your email and I'll link you to it and you can check it out" "No forget it I'm not bothering with my email".
Just let us have a way to quickly and directly link them, don't involve email.
