Either an edit or a preview. Either way I support.

Editing within a time limit and a preview button would be so helpful.
Too many people who post controversial opinions would just backpedal if they could delete at will
Yes. This. Literally couldnt have explained this better.

I'm not sure about editing comments as it could end up confusing if people change their comment too much.
I do think a preview would be a good idea though.
I would LOVE the preview option! I'm on the fence on the edit - mostly because I don't know coding to know whether a time-limit would be easy to put on it. If so, sure :)
But to my own surprise, I'm not up for the pagination. I thought I would like that, but just as brought up, I ctrlF for staff comments and use ctrlEND to get to the start of the conversation, and pages would make that messy and annoying. :(
I vote for a preview button.
Also a small time limit to be able to edit.
I could live without editing if I could delete my comment and try again. But editing would be nice.
