Much like the "bless" command used by administrators, Sanctify is a new Everything2 Level power (available at Level 11), which allows users to give another user of their choice 10 GP.
Users who have the Sanctify power can make use of it at the E2 Gift Shop, by using the /sanctify command in the catbox, or by using the link which appears at the top of the page whenever they visit another user's homenode.
Upon sanctification, the GP is transferred from the giver's account to the receiver's, and Cool Man Eddie sends the recipient a message informing them that they have been sanctified.
Unlike the bless command, being sanctified does not increase the recipient's number of Golden Trinkets. It does bestow a Silver Trinket, however!
