Nope, that lets the SA define a list of tags, and turns the freeform tag entry into a checkbox thing, like the category meta box, and makes it impossible for non-SAs to add ANY tags (they can only use the ones entered by SAs). I want them to be able to add tags just like they do now, just not one specific word.
I'm trying to create a featured post area for my main site (to highlight one child site post of my choice) without using a plugin. I was going to hardcode the display of the latest post bearing the tag "featured" into a custom template for use as my front page.
ETA: I'm currently using Featured Content Gallery, the edit post meta box for which I've modified to only be visible to me (SA), so if I see a post pop up in the feed of latest posts that I like, I can click in to it's edit screen, tick the "featured" box, save, and voila. Only issue is how it displays the posts (slideshow).
What would be ideal is something with a backend setup like that (tick a box that's visible only to SA on each post's edit screen to feature), and have the output be static, and display a different marked-as-featured post each time the page displaying the output is refreshed.
ETAA: I do use the Sitewide Tags plugin, so posts are actually imported from child sites to my main site, so that part is taken care of. I just need a quick and easy way to mark a post as featured (and clicking the post, taking you through to the child site, then clicking the edit icon, seems to be the quickest way), and then display those in NON-slider form on a templated page.
