I saw that there was no tag wiki summary for legend-of-grimrock yet, so I was going to add it. However, I don't seem to be able to get to the screen that lets me submit an edit.
When I click on the help us create it link, I get taken to the tag's info page, with no link anywhere on there to suggest an edit. I know I've submitted tag wiki summaries in the past... has there been a reputation change or some other bug preventing me from doing it now?
Update: It looks as if I can improve existing tag wikis. I just can't create brand new ones.
