 Introduction
 ============
 
-This module stores presence from users contact even when they are
-offline, so that the client can see who is online faster when they sign
-in, and won't have to wait for remote servers to reply.
-
-Note that in its current form, the number of presence stanzas sent to a
-client is doubled, as the client would get both the cached stanzas and
-replies to presence probes. Also see [mod\_throttle\_presence].
