Profile needs a lot of cleanup work, but I went in and removed the <ref> tags </ref> that were after the Sources header (those WILL throw up DBEs) - and I stripped out the html code I saw, because Wikitree does not use html coding, it uses wiki markup language (or whatever the actual term is).
Those long links just need to be texted down using the [square brackets], thusly [humongously long url here (leave a space) text explanation of the link here].
It seems a lot of what is currently sitting below the Sources header could be placed in the biography section.
