Howdy!
I don’t want to grumble too loudly, but anyone that sends a message to “spark@sparkfun.com” about potential widgets really should get some sort of reply in fairly short order, even if it’s a “Thanks for the idea, but…”, or “We’ll try get back to you…”
Obviously, the e-mail gets sent into the ether and the sender has no way of knowing anyone even received it, or read it!
For a bit of a shameless plug, I did submit some products I have on my (very new) site, which I thought were pretty cool, and seemed to be right up SparkFun’s alley!

Thanks.
