Thanks Ian, we're glad you like the new features.
The categories need a bit of a sort out at some stage, with better organisation. For instance, for the seasons at the moment we list 'Springtime in England', 'England in Winter', 'English Autumn' etc. It would be far better to just have a main category of 'Seasons' and then sub-categories under that of Spring, Summer, Autumn, and Winter, making each category easier to find and easier for members to list their pictures under.
When we get round to this sort out, we'll look at ways of allowing members to add or suggest new categories. In the meantime please feel free to suggest a category here in the forums or by dropping us an email and we'll see what we can do.
