Don't bother asking yourself "Wtf is this thread?" and instead just take notes.
If you've played Zapk's Prop Hunt server, sometimes those pesky props get in to the museum and you need to find a way in to chase them down, so you have to call over a friend to jump up on top of to get on the roof. However, you can do this alone by utilizing a ramp:
http://www.youtube.com/watch?v=AKKu1SvOUlg1. Stand on a ramp and jump to the top of the white building by holding W or S (do not press A or D)
2. Face the museum and tap W to slow yourself down (do not start moving forward before step 4)
3. Continue doing this until you are far back enough to do step 4 and jumping almost straight up
4. Hold W so that you land while moving forward and as close to the edge of the flat surface as possible
5. Raid the exhibits!
Everyone knows if you jump down a ramp you start to go faster, but no one's ever really found out why/how/how to control it. For fun, I've been attempting to do so, and this is an example of how you can gain noticeable distance with minimal pre-jump space. Plus, it's not just "look how far you can go," but a useful technique in one of the more popular gamemodes recently.
The key to the technique in the video is that you began jumping by standing on a ramp, and there's a bit more to it like the direction of the ramp but I can't fully explain it yet.
Strange kind of subject for this game, I know, but there you go.
I moved this from Gallery because I'll eventually turn it into a topic all about speed control.
