Guide #1: Usually, yellow text looks terrible considering that Sythe's skin is mainly blue, but yours looked exceptionally beautiful because it matched with the images you posted. I had no window stretching problem, but that's because I have too big of a monitor.
The guide itself is great, and you've picked a nice topic to write on since not everyone on Sythe owns a badass PC and could use that extra RAM well.
Guide #2: Yet another great topic. Nothing much to say other than that you can manipulate stuff quite well.
Typo:
What is need you might say?
"What is needed, you might ask?"
Guide #3: The title made me think it was going to be a guide for total dummies who can't even figure out how to stop WLM through the Options menu, but after reading through it, my view changed. In all honesty, it should be 'How to stop any program from popping up on start-up' or something, as the method that was included in it appears to work on more than just one program.
Conclusion: All three guides were written well, and all of them seemed helpful in my eyes. If the next two are of the same quality, your chances of getting into the team will be extremely high.
Good luck.
