I need to warn you all that if you are considering signing up with Skinbook: forget it! This site has the most flakiest and despotic admins and moderators that I have ever had the misfortune of encountering (just next to David Cheetham aka bushnud from the South East Queensland naturists group).
One of them apparently is not even a naturist or has taken part in social naturism for that matter. Cheri Alexander was kicked off the group by the mods, and a couple of them deleted forum threads because some of the posters made comments that THEY personally did not agree with without warning instead of simply closing them.
They also barred people (including myself) from the site without any prior warning or giving notice as to why, even though I did not disobey any of their rules. Several other people whom I know suffered the same fate, and are very cross about it.
It's a shame because the site started out with such promise and now looks like imploding within itself.
If there is a network on ning that you would be better off joining it is this one:
