I like the comment extension you made, i just have one issue with it.
I want registered users on my site to be able to use tags in their comment to link to YouTube video’s with the use of the allvideos extension I have installed.
This works fine if the tag is used in an article but when the same tag is used in a comment, only the tag text is shown instead of being executed to show the YouTube video.

I can't get this to work
Can this be done in your comment extension ?
