I have looked at aewebworks quite a bit in the past (I'm a bit of a script junky
) - I did some extensive testing of their demo site and found it full of bugs, when I spoke to the people behind it, they claimed to have fixed them, but it still didn't do what it was meant to (it did look like a brilliant system though).... Since then they have emailed me to tell me it's fixed again, but I haven't gone back to look at it....
