We are curious why you are using #c-c-c as a TOPIC-Tag?? That TOPIC-Tag is used to indicate a post is a CURATED COLLECTION... But this post is obviously not a collection of links. Therefore we're confused and perhaps there was a mistake by us not helping you to understand what a collection is? Or perhaps you're using #c-c-c for another reason?
first topics are special and can't be removed after you publish. So just remember for next time and we'll work on trying to make sure people don't make that same mistake i guess. Did you press it while in the advanced menu and then forget to remove it before publishing? Any wording we should add to make sure others don't have this mistake?
