@MF416 This is the blog copy pulled from the top version of the blog draft. Please let me know if any copy should be replaced with @liam-ohagan's version. I had to replace the colon with a comma in the title to avoid errors

@asilinphoto Can we pull the bottom copy (edits w/ Liam)?

Just need to wait for updated Publication posting so we can actively link

@MF416 please let me know if you'd like any tags added to this. It can make searching for a post a bit easier on the front end

@asilinphoto any recommendations on tags to add? I don't really have any experience with this / not entirely sure what you mean by tags

[MF416]

@asilinphoto anything else needed to launch?
