Across the internet, there are several new DSi website attempts a day. We just don't know where to look.
For example, I have found a DSi website called DSiCurse, a simple, constructive, and fun website. I have advertised it across the chatrooms today, but word has not gotten out quite yet.
http://dsicurse.phn.me is a professionally written (here meaning professionally created) DSi website with many of the same things popular DSi websites have - chatrooms, forums, etc. But, DSiCurse has a few things other DSi websites don't - a STORY BOOK, a STORY SUBMISSION, a policy that all story submissions will be included in the publication "The Best of DSiCurse" (publication meaning a book that will be published and sold with yearly issues). DSiCurse is created by author Lewis Hutchens, a fifteen year old living in Golden, CO. He has only one novel on the market currently and has NOT advertised this.
