I'm confused about what would happen if I sync my LC account to my LCCN account.
I know all my coins will be transferred (why though?).
Also, if contest records aren't synced, does that mean that in the future, if I participate in a contest, it will only change the rating of the account I used for the contest?

Also, if I do anything else (like solve problems) in my LC account, will it show up on my LCCN account? And vice versa?
Or will my LC account just be deleted?
Thanks.
