The Klik of the Month Klub meets right here on this very website on the third Saturday of every month at 4pm PDT for a two hour Klik & Play Showdown. Everyone who participates gets two hours to create something from scratch in Klik & Play. Abusing the stock objects is encouraged. If you really loathe Klik & Play you can use whatever game development platform you want. Two hours is a pretty tight time limit, though, so choose wisely!
Some Klikmongers have made a KotM N00B FAQ that might ease your way into Klikking with the best of 'em, as well as a Learning KNP FAQ.
Klik & Play is absolutely free to download, and learning it takes minutes, so everyone can get in on the action. Want to talk to your fellow Klikwreckers? Join us on IRC -- server irc.freenode.net, channel #glorioustrainwrecks. Join the mayhem!
