Is there a way to see posts you have --? I had to stash phone in pocket quickly before I could close devrant and I accidentally pocket -- somones rant but cant find which one so I can fix it..

Too late. The person has already experienced the searing pain of being downvoted on the Interweb and has probably questioned their value to society and put plans in place to end it all.

Best thing you can do is put this behind you and spend the rest of your life trying to make amends by upvoting everything you read---regardless of substance.
