[21:27] Ina Centaur: On the Client menu, there's an option that says "Recorder" -- the submenu leads to choices like "start recording, loop playback..." --- what is the Recorder suposed to be used for?
[21:31] Frontier Linden: Evening
[21:32] Ina Centaur: Hello.
[21:34] Frontier Linden: I am unable to find any documentation on this feature
[21:35] Frontier Linden: I would recommend not touching it
[21:35] Ina Centaur: I've touched it, and it seems everything is lagging.
[21:35] Ina Centaur: I assumed it either records every key press, or at least the chat transcripts.
[21:36] Frontier Linden: Please relog into Second Life
[21:36] Ina Centaur: However, that doesn't seem the case.
[21:36] Ina Centaur: Would you be able to forward my question to someone who knows this feature?
[21:37] Frontier Linden: OKAY
[21:37] Frontier Linden: Please relog
[21:37] Frontier Linden: Thank you Ina
[21:37] Frontier Linden: I must take more calls
[21:37] Second Life: Frontier Linden has left this session.
Note: No reference number given... He didn't say "I must make more calls," implying that he'd forward the message, but rather "I must take more calls."
