You may have noticed that getting "ungreyed" for one Kinja blog does not mean you're set for all Kinja blogs. Same holds true for blog authorship. By default, you are an author on your "Personal Blog" which is really just your user account page. If you've been lucky enough to get added to the author rolls on a blog like Hackerspace , Whitenoise , TAY , or otherwise, you have additional posting options in the "Compose" screen (see below). You will also be able to "reshare" from one Kinja blog (like whitenoise) to another (like Hackerspace) from the "Share" button on the original post. (See the bottom of the page for a screenshot).
