I am so very glad that you pointed this out. You didn't miss anything, somehow I deleted your registration information (along with a bunch of others). I caught the mistake because I saw your post in this discussion forum and wondered as you did, what went wrong. You are back on the list at #164, a little farther down because I didn't think it was worth renumbering.
Thanks again for pointing out the missing entry! And glad you are interested to learn more about WikiEducator and wiki editing (I noticed you already know how to add a row to the table).
Sorry for the mistake.
