where is the jitsi log? On Linux, I can "tail" the jitsi log:

thufir@tleilax:~$ 
thufir@tleilax:~$ tail .jitsi/log/jitsi0.log.0

However, I wasn't able to find a .jitsi directory specifically, or configuration files for user applications.  Are they generally in the home folder?  Specifically, where's the jitsi configuration and log, please?

My system:

  System Version:   OS X 10.10.2 (14C1510)
  Kernel Version:   Darwin 14.1.0
  Boot Volume:  Mac OSx
  Boot Mode:    Normal
  Computer Name:    A MacBook Pro
  User Name:    thufir (thufir)
  Secure Virtual Memory:    Enabled
  Time since boot:  1:03
Jitsi → Preferences, then selecting the “Advanced” tab and opening the “Logging” form. You’ll see the “Archive Logs” button in there.

If your jitsi version is above 2.4 or newer, you can find log files in ~/Library/Logs/Jitsi.
