The weird part;
When I inserted some text and selected then click the "parse as quote", I then clicked cancel on the popup, but then it removed my text and replaced it with my clipboard.
Suggestion 1: When you click cancel on the popup, is it possible that it will just write
Suggestion 2: In order to make it easier for users to insert dates/users in quotes, how about
|Svip|I love pie|
|[quote=Svip]I love pie[/quote]|
so it wont ask for the attribute.
