comment Variation of the determinant of a Jacobian
@Buco: Hover the mouse over the comment you want to delete. An "x" should appear at the end of the comment. Click on the "x". Bam!

comment Variation of the determinant of a Jacobian
Hi @Buco. You can only edit a comment for 5 minutes but you can delete it anytime. So the trick (for a LaTeX-heavy comment) is to store the comment in an external editor, copy&paste into a new comment, edit for 5 min, delete, open a new comment, edit for 5 min, delete, open a new comment, etc, until you are satisfied with the format of the comment. Alternatively, you can try flag a moderator, but I doubt he would be too enthusiastic about having to clean up other peoples comments.
