Since everyone with a RepRap is technically a RepRap developer, it should get fairly crowded in there. No worries, we're friendly. And we want you to help us make RAMPS better.
For sales and chatting with the all the numerous, multiple vendors of RAMPS electronics ... please go ... hmmm ... not sure. This forum is more for-getting-it-working type support. Try the marketplace forum if you want to buy stuff, and if you're really frustrated by he-shipped-a-box-of-rocks issues, or where-is-my-stuff issues, please try the general forum ?!?

Remember, you're all RepRap developers (once you've joined the super-secret developer mailing list), and the wiki, RepRap.org, [reprap.org] is for everyone and everything!
