I didn't notice that red warning, but I remembered your warning in this thread and took the chance. Live dangerously!
As far as I recall, I've only used BB codes like [ b ] in blogs.
In this case, the links were broken until I went in and chose "Edit". After, they were fine. This was not a complaint or plea for help, just a comment that some links "came back to life" for me. (FF 28.0 and Windows XP Pro)
But there was no "square bracket" BB code on those links, just "http colon etc".
They didn't have the descriptive-text-with-URL-hidden format like my sig block, just naked old URLs.
