I am excited to announce that blogs are now available on 17th Shard! They aren't skinned 100% yet, so please keep in mind that the design is a work in progress, but we've fixed the whole "lack of a background" problem that was plaguing us before. To start a blog of your very own, go into your drop-down menu (the one next to your avatar in the top right corner of the page) and select "My Blog," then follow the prompts. Or you can click on the tab labeled "Blogs" at the top of the site to see what other members are writing.
Enjoy, and happy blogging!
