Blokhaven is a place to build a figure, kit it out and show it off. There is nothing to download and nothing to install: everything on this site runs in the browser.
1. Make an account
Go to the sign-in page and choose Create an account. You need a username, an email address and a password of at least eight characters.
Pick a username you are happy to be known by. Changing it is not possible yet, and when it is, it will not be free: a name that keeps changing is a name nobody can trust.
New accounts start with 500 Coins and a few items already owned.
2. Dress your figure
Open the avatar editor. Your figure has seven slots: face, hair, hat, shirt, pants, back and a held item. Pick a skin tone, try things on, and press Save when it looks right.
Nothing is saved until you press Save, so try the silly combinations.
3. Buy something
The catalog has every item on the site. Sort it, search it, or turn on only what I can afford and see what 500 Coins buys.
Read Coins and Gems before you spend much.
4. Say hello
The Introductions thread is the usual place to start. Posting on the forums covers how the formatting works.
