Allan,
have you had any time to take a look at the linking commands that will allow for easy insertion of Markdown, HTML, etc? I've been playing with the Yahoo-Ruby interface and have some new commands that allow for searching/linking in different areas (news, videos, urls) and finding related suggestions. I don't want to bother sharing it with my same old HTML tag insertion if there's a linking library of some sort on the way...
Thanks, Brett
