1- Don't keep multiple drafts for a subject (post/pm) just keep the latest version.
Absolutely not. The handful of times I needed a draft it was usually some old version of a post where I messed up bbcode and wanted to go a few versions back.
Type long posts in a text editor and paste into the forum once you're ready. Or send a PM to yourself if you really don't want to use any other software.
You are rehashing backup shit. Backups are great but utilities are great too. Is it that hard to chew? As I said using Word is not an option for me to make drafts for my posts in btctalk. I've tried it multiple times it just doesn't work, I become distracted and lose the theme. It is why I need drafting support, no need to trolling anymore.
Sounds very much like PEBKAC and not in the forum software.
