#
# have a look to "T" argument, it is not sanitized before to be used in our
# INSERT query, so we can inject all the values we want and store them
# in the c_messages table. Also it is not delimited by quotes & we do not need
# quotes to extend the query, so this works regardless of magic_quotes_gpc settings
#
# sprintf() should be passed to an eval() near line 197:
#
# ...
# // "System" messages
# else
