Username rules

Usernames must be 3 to 30 characters when spaces are ignored. Letters, numbers, spaces, underscores, and hyphens are allowed. Capitalization and spaces do not create a different username, so “MapleSeller” and “Maple Seller” are treated as the same identity.

Change it

Open Account settings, choose Edit profile, and enter a new username. SellUp checks availability while you type. Save only after the available confirmation appears.
