HandsAndFeet is a project mainly written in RUBY and JAVASCRIPT, it's free.
A pretty basic rails app for now, adding features as I watch the railscasts...
HandsAndFeet is evolving; started out as a simple app to add users, require authentication, and do some cute tricks I've seen in the railscasts from ryan bates, such as sortable columns (ascending/descending), pagination of results, search, and now specifying which views require an authenticated user and which ones do not using a before_filter in the main app controller.
Plans are to add blog with comments/comment editing, then a needs/wants database for our homeless population. I've been using a Mantis database for that, but it has a fair amount of cruft associated with S/W problem reports. I've been working with CAP and have been eyeing Farrel Lifson's RCAP project:
https://github.com/farrel/RCAP.git
but I don't know that I want to fool with full-blown CAP messages for this...
This is pretty much newbie-see-newbie-do code, learning as I go...
