<email> The email address associated with the account.
<password> The password for the new account.

Usage: REGISTER <channel> [<password>]
<channel> The name of the channel to register.
<password> (Optional) The password for the channel. If omitted, the channel is linked to the currently authenticated nickname (account) registration.

This command allows users to register a nickname (account) or channel. If an email address is provided during account registration, a verification email is typically sent. Channel registration requires either a provided password or an active account authentication.
