So I should created one logger (fe. named "users") and add to them only one - my own appender that will be distribute events to specified file appenders? (it will be check to which context of user it should write, it find this user file appender and call for them append function?) In each case, when i call function debug, info etc, I select right file appender (in this way to call append function?) (If I exactly good understand?) I don't know exactly how to protect main logger won't to write to many user files (file appenders) simultaneously. regards chris
