Greetings to all!
I am a contributor to gitHub. My most recent ROR contributions to gitHub has been at the App level from my new web-site: www.echomarket.org. I think that some of you will find some interesting code there: edit, reuse, and new in a single form; Search with an interesting model and zip-code functionality; dynamic row addition/edit within a single form; use of JQuery to enhance user interaction to name a few aspects.
Anyway, my attitude and purpose in using ROR and creating web-sites is to foster community-building -sharing from a website. The purpose of www.echomarket.org is to introduce borrowers and lenders in nonperishable/ethical sharing, donating and/or recycling of items.
