I am in the same situation as Richard and I second that 3.3 ad13 is very reliable. Another reason why I personally still stick with 3.3, apart from the reasons Richard put forth, is that virtual hosting with Jerry Asher's nsvhr/nsunix allows you to shut one server down without necessarily and simultaneously bringing the other ones down. I find this feature quite important in at least some situations.
Are there alternatives to nsvhr out there that are documented and that let you do the same but with AOLserver 4?
