I get depressed when my phone deletes my nice post, and signs me out.
Ahh, what happened?! Incase you didn't know our forum has a special feature which auto saves your post as a draft while you type it. Now I'm not sure if it'll work on mobile mode (I'll look into it) but here's the link to how you can activate the feature - Auto Save Post Drafts. I wish it's a feature that can be activated by default but unfortunately I can't do that yet.
Knight...i know just how you feel....its sooo annoying because its happened to me lots of times and i almost cry lol especially when its a real long post lol
