The hyperlink feature doesn't work at the moment but hopefully it's something Josh can get fixed. In the meantime, you can override it to get it to work. Highlight your text and click on the

[url]Facebook Page for the Unofficial Taylor Guitar Forum[/url]

[url=https://www.facebook.com/pages/The-Unofficial-Taylor-Guitar-Forum/172404706190182?sk=wall]Facebook Page for the Unofficial Taylor Guitar Forum[/url]
Then it will look and work like this:
