[Design-team] F13 Wallpaper questions

Hi, I am considering contributing into F13 wallpaper (or trying to propose another trash concept). But I would like to ask few questions first (sorry these are all newbie questions): 1) how much time is left for F13 concepts? As far as I understand there are some dates: http://poelstra.fedorapeople.org/schedules/f-13/f-13-design-tasks.html and wallpaper concept design will close on Mon 2010-02-08. More specifically, after this date only those concepts will be elaborated more which were submitted by Mon 2010-02-08, am I correct? 2) do I understand it correctly, that after this there will be only 7 days to finalize selected concept to a production quality (Finalize Alpha Wallpaper)? 3) is there any technical specification for F wallpapers? I.e.: resolution(s) for single - dual screen configuration, recommended colors for F13 release, etc ... 4) I did not have a chance to follow theme discussion for F13. Is there any limitation/recommendation about what should/should-not be depicted in F13 wallpaper? 5) Is it important which SW is used to create F wallpaper? In other words, does it matter if Photoshop is used? (I don't want to start flame wars, I just did not have enough time to learn GIMP better so far, also I am not sure whether my good-old Wacom Artpad will work with Fedora. I use Fedora as a SW developer on a daily basis but did not use it before as a graphic designer...) Thanks and regards, Lukas Vlcek
