The blog feature of Web For Actors is experimental. If you however are interested in setting up a blog on your website, you have 3 options. One of these options is: MEDIUM.
Medium is an online publishing platform developed by Evan Williams, and launched in August 2012. It is owned by A Medium Corporation. The platform is an example of social journalism, having a hybrid collection of amateur and professional people and publications, or exclusive blogs or publishers on Medium, and is regularly regarded as a blog host. We utilize their API to host your blog right on your website.
If you chose to use Medium on your actor website, you'll have blogs both on your Medium profile and on your website.
You can create your free medium account here.
