A couple of days ago I launched Rails Kits (http://railskits.com/), a
place to get ready-made Rails code so you can get your projects done
faster. The first Kit is the SaaS Rails Kit (http://railskits.com/
saas/), which will save you the pain of writing recurring billing and
account management code for your subscription-based site.
Check out my blog post on the release for more info:
