Hi Ben
Correct me if I am wrong & unless it has been changed since I tried one day, It's just an thought -that you make it possible for the poster to edit their individual "posts" after being submitted.
I know I have done it once virtually straight after submitting it with an edit button then a few days later wished to edit it to add extra or correct something & there it no edit button - other forums seem to have no time limit on this feature.
Just a thought.
Cheers
