A couple of the obvious features I like are that it’s written in Perl and has a good security policy. Of course, TWiki is written in Perl and has a security alerts page, so that doesn’t guarantee much. WebGUI is shipped ready-to-go in binary form, and is ostensibly pre-configured, which I figure should save me from making too many foolish mistakes. Time will tell.
I’m going to give it a go on my main site soon. Photos don’t put themselves on-line!
