I'm either blind, or it's not there

1. How can i access my favorite posters?
2. Where can i find country codes for filters?

1. They're in your own profile, just click your name up (where it says "Welcome, graf_z". Both your favourites and your uploads will appear.

2. It's in a page of the forum, but it's obviosly too hidden. Not sure why it's not in a more visible place yet.
Country Codes
That page was made provisionally, but I think it has became the only option. So of course, it's not your fault you haven't find it on your own, but ours.
