 A guanote can be sent to a flock or an explicit collection of flockrs. In the later case end users can enumerate the targeted flockrs in the receiver list or take a snapshot of a flock. It is important to note that if the receiver is a flock, the guanote dynamically recomputes the flock definition at every device to which it gets propagated to determine the targeted flockrs. If the receiver is the snapshot of a flock, the guanote directly contains the list of targeted flockrs. A guanote can be sent to a flock or an explicit collection of flockrs.

-The above figure illustrates the propagation of a guanote in a campus-based scenario. It shows six flockrs connected in Urbiflock and running the Guanotes application. The communication range of their devices is depicted with a dotted line while the colored dot on their devices denotes the gender of the flockr (pink for girls, blue for males, and grey if the gender is not set in the flockr's profile). In particular, the figure shows how a "hallo" guanote is sent by Elisa to the //nearbyMaleFlock// (defined as all nearby male flockrs). This guanote is transitively propagated until all connected flockrs belonging to the nearbyMaleFlock are reached. The guanote is not propagated to flockrs that do not adhere to the definition of nearbyMaleFlock. The guanote is first propagated to Stijn and then to Wolf. Elisa's device is in communication range of two devices (corresponding to a female flockr and Stijn), but since the guanote is only meant for male nearby flockrs, it is only propagated to Stijn. Similarly, Stijn's device is nearby to Elisa, Wolf and a female flockr, but it only propagates the guanote to Wolf. It is important to note that Wolf receives the ``hallo'' guanote without being in direct communication range of Elisa's device.+The above figure illustrates the propagation of a guanote in a campus-based scenario.
