What forum software are you now using? I hit a button, and lost my entire post. After a deep sigh, I found the thread again and scrolled back to where I was, only to realize that the forum software had magically saved a version of my post!!! So many wonderful new features: the like button, the icons showing which threads I’m following, and Alerts … NOM NOM NOM.
It’s been there for a while, though I haven’t figured out how to get rid of those saved posts - not that it matters. But I’m the type of person who sometimes writes a long post, then goes “nah, can’t be bothered getting into this discussion” So there are few abandoned posts hanging around in some threads.
