Meta Stack Exchange is where users like you discuss bugs, features, and support issues that affect the software powering all 158 Stack Exchange communities.

What is meta?
Here's how it works:
  1. Any Stack Exchange user can ask a question
  2. The community provides support, votes on ideas, and reports bugs
  3. Your voice helps shape the way Stack Exchange operates

I have read an answer to a question, which is subtly wrong, but was upvoted possibly for the nice explanation. Now I don't have the rep to comment on the answer, and I don't want to down vote it either because well, again I don't have the rep and, worse, no one learns anything this way.

I tried to edit the answer to clarify where the author went wrong, but my suggested edit was rejected. I wasn't aware that those sort of "comment-like" edits were not acceptable. Just to point out, the suggested edit was rejected by the difference of just 1 vote, meaning that there were some voters who actually saw the point of it.

I'm trying here again on meta just to get my point across. The answer I'm referring to is here: I don't want to down-vote, just a simple comment explaining that the exponent's sign is not done by a sign-bit but actually done by biasing, and so 111 is actually a valid (4) and not (infinity).

Was there something simpler I could have done but I just missed it?

Suggest an edit on a different question..? – ben is uǝq backwards Mar 12 '13 at 13:19

Keep the answer in your bookmarks (or bookmark the question by clicking on the star below the score), accumulate enough reputation for commenting (you only need 50, it's very easy for someone serious), after you've got enough reputation, return to the answer and comment.

Don't use:

  • Flags (moderators won't handle technical innacuracies, don't try).
  • Edit suggestions (to tell the OP about the fault. Correcting it is OK)

Edit: You now have the comment everywhere privilege!

Good luck!
