Hi Tareq, I'm sure the team will join me in welcoming you.  One note
-- I think the team is no longer taking wallpaper submissions for the
F12 extras package, simply deciding on the ones already up for
consideration.  However, you can easily make a wallpaper available in
your fedorapeople.org space, and/or wait until F13 to contribute to
this worthy cause.  Thanks for your work on Fedora!

Also, if I'm wrong about the above, I'm sure Mo, Nicu, Martin, Maria,
or any of the other wonderful people here will correct my mistake! :-)
 Thanks paul, maybe in F13 :)
As you said i'll be putting all my creations in my fedorapeople page.

Well, in the other mail I sent to the list about extras I suggested that
we still accept wallpaper submissions for extras till this Friday, but
only finished ones (plus unclear licensing/missing links used sources
are a showstopper), no one objected so far so I take it as that's what
our position is on this now.
 I can't do that all in time.
But no problem, as Paul said i'll do it in F13

And welcome to the team, Tareq :) 

Your submissions however violate our rule to not include fedora logo and
text in wallpapers, other than that they look beautiful, IMHO the
aurora1 is better :) Is it all original work have you also reused some
art from others?
Thanks, i didn't know about fedora logo thing
It's all my work (Genuine)  :)

Thanks All
