My community has an 'official' website with a blog and a forum but it is proceeding so slowly that they still have clip art on the main page two months later and more bugs than a summer afternoon so I built a Ning network. http://monmoutharts.ning.com/
So far things have proceeded well, I can upload photos from Flickr to the site then share photos on a Facebook application that almost 100% works almost. I can upload Mp3's video and write and share links.
One thing I haven't found is a way to make a list of links (to my local arts sites) does anyone have any suggestions?
