The submission phase for the supplemental wallpaper ended last night. The
voting for them is open now and its only until 17th of September you can
cast your vote.
We have 151 candidates in the pool, so its a hard job as some of them are
very good. On the other hand its easy to find 16 wallpaper you like.
We use Nuancier for the voting https://apps.fedoraproject.org/nuancier
everybody has CLA +1 can vote.
