These two pages are almost identical:
Except for some little differences. Help center links to 1, the magic link [ask]
points to 2. There are "related articles" in the sidebar of 2, but the sidebar of 1 is filled with links to other Help Center articles. There's a search bar in 2, but not in 1.
I vote to close one of these pages as a duplicate of the other.
Same story with answering: one page in Help Center, one linked from [answer]
magic link.
