Im only 15 years old and i have no experience using Macs but I was wondering, is there any way to delete the login logs from Mac OS X 10.6.5, like when you go to the terminal and type -last, those kind of login logs. And also is there any way to delete "All Messages" and "Console messages" from the "Database Searches" (the first row of the log list when the console is opened.) PLEASE HELP
