Auto-Saves your post drafts on altcoinstalks.com
made this userscript which adds a draft and auto-saving functionality to the forum.
Since the forum has no draft functionality, the script saves your partial posts to the browser's local storage.
By default, the script saves up to 10 drafts, every time there is a change to the post:
a) when you click preview
b) every 60 seconds
You can change the MAX_DRAFT_HISTORY and INTERVAL_SECONDS variables at the top the script.
[To disable the automatic draft every X seconds, set the INTERVAL_SECONDS variable to Infinity]
