If you have to embed it in your site, and in your site only, forget about sockets, xml and other "complicated" staff.
3 actions (getmessage, sendmessage, checkmessage) 2 html pages, a bit javascript (for reloads) and 5-10 classes on the business logic will be enough. Don't make things unneccessary complicated :-) Regards Leon P.S. if you find that you need a more complicated solution in 6 month, you still can develop it then. Develop now things you need now, don't look for tomorrow :-) (X.P.) > -----Ursprüngliche Nachricht----- > Von: Miquel Angel [mailto:[EMAIL PROTECTED] > Gesendet: Donnerstag, 5.
