A technical question: I've uploaded my photos and want to make sure that they're visible to SOLWorld people only, and not the whole wide world. I think they are currently set to be seen by 'friends only'. I don't know if you can see them if you're not a friend of mine!? Perhaps someone can let me know? The photos seem to be showing on the main SOLworld Ning page even if you're not signed in? Does anyone understand the privacy on these?
