I mean that even on a community where your tag options are limited to your character's name you could have your post and at the end of it still within the body of the post add fake tags to add flavor to the post if there are certain things you want the reader to be able to see. They would not be actual links. They would just look like tags. For instance if tags are a point size smaller and blue then you'd code them to look that way. Or you could use a hashtag (#) like they do on Twitter.


Examples:

This is my post where I'm posting things and you are reading it and eagerly responding to me!

#cursedagain, #grabbagnightmare, #cleverexamplehere

or

This is my post where I'm posting things and you are reading it and eagerly responding to me!

cursed again, grab bag nightmare, clever example here


Since they would not be functional for you, they could just be in addition to utilizing the memories option where you can set up the words or phrases it links to and use them similar to tags.
