Mine says you're provisionally added, meaning you have yet to add me. What I mean by not having touched it is that I haven't edited it on my profile since last night, or ever, so mine is correct. :/ I dunno what's going on. Did you maybe hit "Local" instead of "Internet"...?
I just deleted the entry, then added your FC again. It says the same thing: your "card" remains gray, indicating that you have not added my FC. I wonder if there is something going on with respect to Nintendo, such that our entries are not registering.
I deleted and re-entered yours as well, and still the same. Yeah maybe it is on Nintendo's side. I'll take a look around and see if anyone else might be having this issue right now.
