Why is the classic wiki editing style used automatically in Opera? It works just as well as with other browsers. I set the User Agent Switcher plugin in Firefox to identify itself as Opera, and the page renders the classic editing style. I've tried it in Opera, and it automatically goes to the classic style unless I set it to identify itself as another browser. This was a hassle for me because I use both FF and OP.

Can I have 2.0 style comment section (blog style not tab style) for my 1.0 wiki? My organization likes 1.0 for its wiki, but 2.0 comment style.
