Registering for a username on ArborWiki is a good idea for two reasons:
- You help build credibility and an identity for yourself by registering a name -- even if it's a pseudonym.
- Logging in hides your IP address from the general public.
If you haven't registered and would like to do so, follow the "Log in / create account" link at the bottom of any page.
Of course, your anonymous contributions are warmly welcomed, if you'd rather not create an account or log in.
