I noticed that you appear to have trouble with the new Visual Editor wikia made default.
You can change your preferences back to the way you used to see the edits by following these steps:
Place your mouse or cursor over your user name in the upper right hand corner of the any pages(in the dark green area on the very top). You shiould see a drop-down menu including "My preferences". *Select "MyPreferences" *On that page, select the "Editing" tab *In the section "Editing Experience", select "Wikia's classic rich-text editor" *Make sure to click the tiny "Save" button at the bottom, and you should be all set.
As you are adding new patterns, I notice that you add Categories as though they are tags. That is not how they work. We have pre-established categories (we are constantly cleaning them up), and they make up pages that list all the patterns belonging in that Category.
You may want to click on one in an estabished pattern to see what I mean.
I am sorry - I thought I had seen 1990 patterns before, but I must have been wrong. As far as the link, that is an error. If I can find the pattern, I will correct it, and I will look for and delete any 1990 patterns I posted.
