I love the publish to Facebook service of LR, but I don't want to have to manually do it every time. Is there a way to schedule my posts with LR?
Not with Lightroom. Does Facebook allow you to schedule posts?
Yes, on Pages. It's extremely helpful when running a business. I can plan my schedule for the week/month. It would be nice to include this feature in the publishing service in LR so I didn't have to export then upload to FB.
Then take a look at Jeffrey Friedl's Facebook plugin. It may be that he worked on this area.
