Reloading is a Simple Action
Reloading any weapon is a simple action across all weapon/ammo types. The result of a reload action, most notably the number of rounds inserted, is unchanged.
Messaging is a Free Action
Sending a short message via the matrix is a free action if the character is actively connected to the matrix in AR or VR mode. Characters not already connected require a Simple Action to send a message (or to activate AR/VR, followed by a Free Action for the message).
Free Actions are More Free
The standard rules allow one Free Action per character per initiative pass. In general, we will allow multiple free actions so long as they are fair and believable.
