My First Puzzle Giveaway. (ended, posted solutions)

Edit: The giveaway is over, the solution is posted at the end of this post.

The giveaway ends Friday night. There's 3 separate parts. For the purpose of this giveaway, use tinyurl.com/jurk with the being replaced by whatever you believe the code is (always in lowercase).

Your first hint: My avatar, what is it?

If this turns out well, I'll do similar puzzles in the future, hopefully with better games. XD

I'll add hints over time as I see necessary.

Extra hint: Pattern recognition and logic.

Edit: first puzzle is 2 characters: tinyurl.com/jurk**

Edit: ALL tinyurls will lead to an image (.pngs usually). or if it's the last one, it will lead to the giveaway.

Edit: 6 hours left as of 3:50 PM PST. (or the post I'm about to make if you're too lazy to convert timezones.)

Solution:

The first puzzle was figuring out what my avatar is. It is Pi in pixelated numbers, collapsed together to remove spaces, and turned 90 degrees to the right to make it a bit more difficult to figure out. this would lead you to tinyurl.com/jurkpi which leads to

from this image, you would get FHLTX which would lead you to tinyurl.com/jurkfhltx
the way you get FHLTX from this image can be seen here: http://i43.tinypic.com/14jbypy.png

essentially, I made A-Z pixelated in a 3x5 size per letter, lined them up, removed flhtx, removed the spaces, turned it to the left 90 degrees, and then made a mirror image of it that I put on the other side of it. I added the before removal and after removal to show that you were looking for what was different between the two.

the tinyurl would lead to this: http://img19.imageshack.us/img19/4172/kakuro.png
it's a Kakuro puzzle, which I love. The description on how you were supposed to solve it was in the image itself. User Reelix posted an image of it solved via a program: http://i.imgur.com/PK0zC.png

The tinyurl you got from that would lead to the giveaway:

yeah, yeah, it was portal, but now that I see this puzzle worked out well, I'll do better games in the future.
