When a post is locked comments and edits are disabled. If a user has less than 20 rep the user cannot participate in chat. How can a user with low rep address a question of theirs which is locked?
Meta is always a suitable venue for raising issues like "why is this question locked?" or "what do I need to do to get this question reopened?" or "I don't understand why I'm being downvoted into the basement here; help?". Locking should be quite rare, so even if you think you "wouldn't want to bother folks on meta" for some of the others, please do bring it here. If it was locked a while ago, it's entirely possible that the mods have just plain forgotten about it. Or there may be a real reason that isn't explained clearly enough in comments, and if so we need to know so we can remedy that.
