There's a good reason I've been neglecting Jough.com for... a while.
Go check out the redesign of Poetry X v3.0, code-named "Nonetheless" since all web projects need code names for new versions.
Included in the new redesign (besides completely re-writing the template engine and backend scripts from scatch to make everything faster and tighter) is a user login system where people can save lists of their favourite poems, post comments, and MORE coming soon.
I rushed out the design before all of the features were ready to meet the CSS Reboot deadline, but overall I'm happy with how it turned out, and am not re-writing a lot of things based on some excellent user feedback (keep it coming, people).
