Last change on this file since 601733d was 6a415e9, checked in by James M. Kretchmar <kretch@mit.edu>, 18 years ago
Added the variable 'aim_ingorelogin_timer', which specifies the number of seconds after an AIM login for which AIM login notifications should be ignored. Defaults to 0 for now. Added the timer object to implement the above and to replace other timers that have been impelmented by hand.
