A couple of minor changes to TOS

[adam]

"Levels, Curves, Color adjustment, Hue, Saturation etc." has been changed to "Levels, Curves, Color adjustment, Hue, Saturation etc. for minor image enhancements".

"Personal snapshots of family/friends/pets are discouraged and may be removed with notice." has been added. This is not a rigid rule, it's meant to be flexible.
