Why are you interested in joining this server?: 
Hey, I was just being me and all until I was all like WHOA MINECRAFT, and then I went to go check on my account and I saw a lot had changed, prior to that I watched a Youtuber named Mumbo Jumbo who did Redstone Creations, and back to when 1.10 (I think) was released, I had a pretty good understanding for redstone and basic commands (such as Tile Drops.) So to sum everything up I just wanna polish up on some of the new concepts for old times sake, a lot of stuff is confusing right now, like how observers work, help would be appreciated. Thanks for readin :P
Current Redstone knowledge: 
Slight knowledge of comparators (used to portray certain signals of redstone based on the status of a object, EX:How much water is in a cauldron.) Not too good with rails, and mine-cart systems. Need brushing up on slime blocks. I also know that you can run redstone into a block a receive an output through that block.
Past Redstone Experience: 
Not really too much experience, mostly played on my friends' survival servers and build stuff like piston doors and automated farms. I also took apart some maps or mini-games that used command blocks and redstone, such as Pizza Spleef and Missile Wars, and incorporated them into "experimental builds (my mini-games, and maps)"
About how often do you play Minecraft?: 
1-5 hours per day
Anything else you'd like to mention? (Optional): 
ALLLL GUDS :D x2 (Also this is a repost of my previous application, since I didn't reach the two line requirement for my responses.)
Application status: 
Approved
What kind of creations would you like to build on this server?: 
I would mostly like to build more compact types of builds that I can fit inside bases, but also hidden at the same time (such as piston doors, or industrial smelting.) I'd also like to build those really cool slime machines that bounce you all sti around the place, while you stay still. Some other things may include experimenting block updates with observers in order to make my builds more compact, as stated in the first sentence.
