Can I move or edit my sticker?

Yes. Your stickers are yours to manage on the Sticker Wall.

• Reposition — drag a sticker to a new spot, and rotate or resize it whenever you like.
• Edit its caption or social links.
• Remove it if you change your mind.

You can adjust your own stickers; you can't move other people's (but you can react to them).
