Damn, got some options to flip through right now.
It's a beautiful sunny day though and some friends are on their way over for some brews in the sun, so I'll go over things tonight, and contact everybody who has repled over the next couple days.
A key deciding factor here will be how the network of choice handles their "420 friendly" members. I know for a fact I have seen dating sites which allowed users to share details regarding their drinking drug use tendencies.
If your system allows one stoner to find another with ease, this will get some big brownie points when it comes decision time. We all want to see these leads convert afterall ;) Be sure to make mention of it if there's a feature that can aid in this respect!
Thanks for the leads, I'll follow up on them.
