Mark,
I was just kidding but there is a disconnect. I guess I assumed that you understood that the markup that you use for ED is the same that is used on almost all forums and it is called bbcode (bulletin board code). This is not something that Kunena invented or that the Stackideas programmers came up with uniquely but instead something that is pre defined and common, and utilized along the lines of, but specific to forums or other text processing interfaces, how you use html, css or even php.
The markup as I stated works in Kunena the same way that it works in ED for quote and code. In fact, in Kunena and ED the markup is identical It is just that in Kunena (and many other forums) there are a few additional options/tags that ED doesn't include such as Spoiler. Off the top of my head, in addition to Kunena, phpbb, vbulletin and xenforo include a spoiler tag for the bbcode offered in their posting interface.
I was not asking for a personal fix but just reporting an issue that will be a problem for EVERYONE using ES / Kunena integration. But thank you for the file.
Paul
