The RSS feeds do load immediately if there a new feed. Every thing seen there besides the wallpaper (the loading 75%), are customizable.
On your keyboard, find the button that says: Prnt Scrn (or Print Screen, or something along those lines, varies from keyboard to keyboard). Then, after that, you can chose a program to paste it on. I usually use Microsoft Paint, just because it takes way less time to load than my other programs. Then, just draw that box next to the star looking shape thing, and press on your keyboard Ctrl + P, or just right click > Paste. Save the image, host it, post it. tl:dr, Prnt Screen > Paint > Host > Post.
Lol, I don't use it, my bro does. Anyway, updated Desktop. I'm using a Vista skin now, with an Object Dock:
no the dock flows nice with the wallpaper. Yours is fine (besides some other things, but i wont complain). But i mean like, when you get rocketdock, or objectdock and dont customize it or anything like that...
