Pleased to hear about your hog visitors. Hopefully some hoglets soon?!
You can upload photos to the Gallery (although it seems to take a while before they appear), but I think you can only load them on to the forum if they are already on the internet somewhere else. I haven’t found a way to do it anyway! If they are already elsewhere, I think you just put the link on. Someone else will probably know better than me! I don’t even know how to put the smiley things on!
