The Live Chat
There is a live chat where members can talk without having to wait for their comments to be moderated. The admins are Kate, Hazelburrow, Jayfrost, Kat and Dawnmist, while the moderators are ShiveringRose, Flowerstream and Flame That Shines Like Sun.
There have been two roleplay sites in the past in which the cats of BlogClan featured. It was fanmade, but deemed official, as it was in association with the blog. However, the first one got shut down, and a little later the second was made, which was also abandoned.
Various fanmade series have been proposed. In the fanmade book project BlogClan Rising, BlogClan is also the main clan. In the first book, BlogClan Rising, it is lead by Nightstar. However, shortly after Nightstar dies, Cakeheart (based on Kate Cary herself) becomes leader.
However, the first book project failed and Rainsong and Copperclaw have started a new one, called Trailing Stars. In this, all of the people that post on BlogClan get mysteriously turned into cats. They must band together or stay in cat bodies forever!
The BlogClan Book, a book composed of interviews with various important BlogClanners, was started by Cinnamonswirl but was soon abandoned. It is currently undergoing a revival.
There are also many fanfic and art contests made by mods. They usually air on holidays and Gatherings.
