Why are you interested in joining this server?: 
I'm interested in joining this server because of a few reasons. First of all, I've been here for 4 days now so far I've had good experiences here. I got to make to friends, chat, build redstone machines and get some help from others too. Second of all, I don't know why it happens - but when I'm building in this server my brain starts to "work". Maybe it's just because it's not a flat boring world like in singleplayer haha.
Current Redstone knowledge: 
My current redstone knowledge is double to quad piston extender (horizontal) and up to triple piston extender in vertical. The things that interest me the most are piston extenders and piston doors (even though I am currently experimenting in extenders and still not building doors). Lately, I've managed to create some very compact vertical piston extenders (You can see them at the start of the visitor world). I also want to mention that someone in the server named zjobke taught me about binary and how it can be used in redstone so I also know a bit of that.
Past Redstone Experience: 
One of my proud creations is a vertical double piston extender, super fast and compact (it only uses 5 blocks, 2 pistons, 1 redstone dust, 1 redstone torch, 1 observer, and 1 lever). The extension only uses 1 block, lever and the torch which is very simple. The retraction uses everything else, and it goes like this: An observer is taking a signal from the bottom piston, sends it to a block, on the block there is a redstone dust and another block on the observer to connect the redstone dust and upper piston. The logic is that first the observer takes a signal from the piston which powers the piston and retracts the upper piston down, and since it got powered another redstone signal is sent but this time it powers the upper piston which takes the block down, and does NOT power again the observer. (If you'd like to see more good creations you can look at the start of the visitor area, I made some compact piston extenders there.)

What kind of creations would you like to build on this server?: 
I'd like to improve my piston extenders and start making piston doors soon.
