Zamiast warnings.on można użyć lms-makewarnings (buduje przekierowania na bazie salda użytkownika) bądź lms-makemessages (buduje przekierowania na bazie ostrzeżenia ustawianego hostom).
Zapewne masz racje :) w zalacznikach zestawik plikow od mojego rozwiazania index.php - osobiscie trzymam go w lms/pages/warning/ do czego config apache ma vhosta na port 81 warning.on, warning.off - to poprostu pliki z regulka iptables warning.check - narazie baardzo brzydko, ale mozna sprawdzic kto ma przeczytane a kto nie (grepuje iptables -t nat -nL) warnings.on - na bazie ktoregos lms-* generuje regolki dla wszystkich kompow z ostrzezeniem
