In the "What do I get for signing up with VRC+?" section, there's some text about "Currently, you get a few things for signing up for VRC+:", but it doesn't mention custom stickers benefit for VRC+ subscribers. Please add this benefit to the FAQ's list of VRC+ benefits.
Oddly enough, (custom) stickers are listed as a benefit on the main VRC+ advert page at https://hello.vrchat.com/vrchatplus but it's missing from the FAQ.
