Hmm, I'm learning a lot as we go along. I've been breaking down what DonC wrote (RudiC's will be next probably tonight when I get home), and I think I just need to be able to tell it not to output any line that returns a 0 (no match found) when this is run:

Code:
match($0, /"username":"[^"]*"/)

I just haven't figured out how to tell it that, maybe I am thinking about this the wrong way.
You're learning quickly. I also submitted something that did it slightly differently, but RudiC posted his before I posted mine, so I deleted it. I am reposting mine here (with changes for CSV format output without the spaces around the commas) hoping that something in your log data contains the string username but does not match the pattern "username":"user@host" (which the code below would treat differently than RudiC's suggestion does):
Code:
awk '
match($0, /"username":"[^"]*"/) {
	split($3, d, "@")
	user = substr($0, RSTART + 12, RLENGTH - 13)
	c[d[1] "," user]++
}
END {	for(i in c)
		printf("%d,%s\n", c[i], i)
}' logs/mycompany.log | sort -t, -k3,3 -k2,2

This can still produce output like you've shown above, if a log entry contains the literal string "username":"" (and maybe also if the second quoted string contains blanks). So, let us know if the above code still produces unwanted output and we can try to track down the log entries causing the problem and eliminate them from consideration.

LIQUIDSOAP(1)						      General Commands Manual						     LIQUIDSOAP(1)

NAME

       liquidsoap - a multimedia streaming language

SYNOPSIS

       liquidsoap [options] [script|expression]

DESCRIPTION

       Liquidsoap  is  a  programming  language for describing multimedia streaming systems.  It is very flexible, making simple things simple but
       giving a lot of control for advanced uses.  Liquidsoap supports audio, video and MIDI streams, and a wide range of  input/output  operators
       including  Icecast and various soundcard APIs.  It can perform a broad range of signal processing, combine streams in various ways, support
       custom transitions, generate sound procedurally...  and all this can be assembled as you wish.  Input files can be  accessed  remotely,	or
       even be synthesized on the fly using external scripts such as speech synthesis.	Finally, interaction with a running liquidsoap instance is
       possible via telnet or socket.

       Liquidsoap scripts passed on the command line will be evaluated: they shall be used to define the streaming system to be ran.  It is possi-
       ble  to pass multiple scripts; they will all be ran successively, and definitions from one script can be used in subsequent ones.  A script
       will be read from standard input if - is given as script filename.  Information about scripting liquidsoap is  available  on  our  website:
       http://savonet.sf.net/

       If  the	parameter is not a file it will be treated as an expression which will be executed. It is a convenient way to test simple one-line
       scripts. When running only one-liners, the default is to log messages directly on stdout rather than to a file.

OPTIONS

       -
	       Read script from standard input.

       --     Stop parsing the command-line and pass subsequent items to the script.

       --debug
	      Print debugging log messages.

       --dynamic-plugins-dir path
	      Directory where to look for plugins.

       --errors-as-warnings
	      Issue warnings instead of fatal errors for unused variables and ignored expressions. If you are not sure about it, it is	better	to
	      not use it.

	      Like --check but treats all scripts and expressions as libraries, so that unused toplevel variables are not reported.

       -d, --daemon
	      Run in daemon mode.

       -f, --force-start
	      For advanced dynamic uses: force liquidsoap to start even when no active source is initially defined.

       -i     Display infered types.

       -p, --parse-only
