I'm sure this is really simple for the right person. I've read extensively from the codex and other sites but haven't figured it out yet.
I want to append query vars onto urls using the permalinks. My plugins only work currently by using the ?variable=x method and I would really like to have them as
or even better
(where 'x' is in a predefined pattern to be recognized)
Thanks for the assistance toward better plugins for the community.
