Possibility to change / delete comments

[Mies]

I think it would be useful and nice if a user could keep his comments (under charts or albums) editable and deletable.
I know there's the "Edit comment" option, but it seems to disappear after some time (even little time sometimes, actually I don't know if has to do with time passed).
Well having them always editable/deletable would be useful. What do you think?

I think would be useful as well, especially when I often sometimes need to correct some grammatical mistakes

You are currently able to edit comments until somebody replies (at which point the ability to edit disappears). This is mainly to preserve the flow of the conversation.
