I just finished some of my last updates on the site for the year! Yay! You can now comment on books and on articles in the "Columns & Reviews" section. (You could do this before but now there is a better system for it.)
I also created a tab for the Bookshelf feature. (Think of if as a place to park that book you want to read next or list of your favorite titles.)
All in all, I'm kinda' proud of Indigo! It's been a lot of work to create it but I think the end results are really worth all the sweat!
