I have a couple stickers that I'd like to put in my collection, but the only option is to send to a friend. What do I do?

You can either put them in your collection yourself for 10,000 sP per sticker by using the Hustler in Pina Park or you can ask someone to do it for you for free. There's a board for it on the Achievements subforum, if you want to try there. :)

Stickers were initially promoted as the only "social" collection, meaning you had to rely on a friend or someone you trusted to put them in your album. This is still true, but you can pay the Hustler (in Pina Park) to stick them in your album for 10k a pop.

There are threads in the Achievement forum where you can find friends to help you with your album :)

Thanks girls!
