Hi Elton, I believe members have an "edit" link next to their own posts for the first 30 minutes after initial submission, during which they can freely edit their entries.

However, you cannot delete a submission after it posted (we don't allow this since it would also affect other members' contributions). If you believe there is a valid reason to delete an entry, you can request a moderator to do so on your behalf. Hope this helps.
