[quote]	- The browser will expel drafts from its LocalStorage once they are 6 hours old to avoid accumulation.[/quote]	What about users who occasionally leave a page open for three days and expect it to still be there through browser restarts and what not? Never mind me unless I raise alarm, though - as long as your system for remembering posts doesn't interfere with my system for remembering posts (which literally brings back snippets from over a year ago in case I left any hanging without posting them) we're all good.

That's a good issue to bring up.

Right now, how I have it working is that once you start editing a textbox, the textbox enters an autosave loop (every 20 sec) until the post is submitted or the tab is closed. If you leave that tab open for a week, then the post should be autosaved that entire time so that by the time you finally submit it, it'll be in LocalStorage for 6 more hours after your attempt to submit it.
