The ability to edit my own answers and questions inline is a privilege given at 2k reputation because it is the same privilege as edit other's answers and questions without peers' review.
But it is difficult to achieve 2k reputation on low-trafic Stack Exchange sites.
Following Dukeling's suggestion, I request the creation of a new privilege, which is a variant of edit privilege but restricted to my own answers (or questions), with a lower rep requirement (at 100 rep ?).
This request would make easier to notify commentators of my answer (or question) that I just made an Edit to answer their comments.
