1. Can't found information about it. WPMU doesn't provide multylanguage user's blogs (the plugins are sucks, 'cause SEO, they stores language information on session or cookie). I mean I want to give my users ability to write theirs posts on different languages in one blog.
2. Does Lyceum have the import tool for Wordpress MU database scheme? I have blog service on MU, and if I decide to move to Lyceum I need to convert MU data into new blog engine.
