If you do, it will k-line you from the IRC server you're using (do you frequent Austnet?) and tell you to fix it. Its a bit of cruel-to-be-kind from the IRC server admins. Its all well and good to have logging, but understanding what it is that you log is somewhat useful too. HTH, D. -- " I don't get mad.... I get stabby. " - William "Fat Tony" Williams.
