Do you have any advice for someone looking to get involved in C&C?
Oh boy, this was so much easier for me to do in gen 5. Bear with me.
C&C is a super cool part of the site, but it has a lot of very technical aspects to it that can get really overwhelming. The first thing I would recommend when you go to reserve a Pokemon, however, would be to make sure you've used that Pokemon and that you know what it does, what works, what doesn't, how to play with it, etc. Experience is really crucial in C&C, and the only people who can pull off writing analyses for Pokemon that they haven't used a ton are ones who have played the metagame a ton and just know what works and what doesn't. After you've figured out what Pokemon you want to write about based off of this, make sure you understand all the crazy formatting. To be totally honest, you don't
have to understand the formatting so long as you follow it. Still, you can read over the new formatting here:
http://www.smogon.com/forums/threads/generation-6-analysis-format.3495073/ There's an copy/paste-able structure towards the bottom of the first post which you can use.
From there, it's just following along with the skeleton and filling in the blanks with bullet points. Other important things to remember in C&C is that QC teams (the people who advise you on your skeleton and eventually approve it), have experience in the metagame, and their advice is generally solid. If you disagree with them, so long as you're willing to justify your decisions and cooperate, you should be fine. Sometimes something that you think is good will need to be cut, and walking into the process with a superiority complex (I know what I'm doing, everyone else needs to listen to me and not the other way around) is a really good way to ensure that you won't be able to work in C&C.
Basically, as long as you know what you're doing, you follow the structure and formatting, and you're willing to cooperate with QC, you'll be fine. If you have any specific questions about the C&C process, message me, and I'll be happy to respond to whatever you need help with.
