I just installed your plugin to post to Facebook. Very nice, but on my post on our website it says xavierfb:
yes. How do I remove that? It looks strange and we don't want that showing on our post on the website.

Hi,

It sounds like your theme is displaying variables stored in each post as Custom Fields. If you turn off the function in your theme or change your theme to only display the Custom Fields you use (i.e. ignore the xavierfb field), then you wont see this any more.
