Regarding today’s fiasco over at Slashdot, where much ado was made about id gathering information on Quake 3: Arena video card usage statistics, I offer into the record (since it appears many have already tried and convicted id without reading documentation) this excerpt from the Q3Test 1.08 README:
== Section 11. ==
== MESSAGE OF THE DAY==
When Quake 3 Arena starts a map up, it sends the GL_RENDERER string to the Message Of The Day server at id. This responds back with a message of the day to the client. If you wish to switch this option off, set CL_MOTD to 0 (+set CL_MOTD 0 from the command line).
