This is an adapted version of the “WordPress Quick Start Guide” of the BScE written by Kristina D.C .Hoeppner. Both guides are released under the Creative Commons license 3.0 BY-NC-SA. The blogging guide for the BScE also includes a few videos (in German so far) that you may want to watch. The BScE Blogs are housed on a different server and thus, things may work a little bit differently.
