Some question about Polyglot

Hi everyone ??
I’m trying to use Polyglot in my blog (www.wererabbit.net/blog), but I found some problems.

1. Despite I’ve modified polyglot.php file choosing the various time and date format, they don’t change choosing different languages, they remain in english. If a use a xx_XX .mo file they change (but Poliglot doesn’t work with them), but with a xx.mo file this don’t work. I use EventCalendar3 too, and I noticed also with it.

2. I don’t understand well how to translate categories. I can just create my categories (in english wich is my predefinited language) in my admin panel and before put translation in the .mo files?

3. I can’t manage to get a post/page title in alla my languages. I’ve 4 languages setted, and if I create a post title like [lang_en]title[/lang_en][lang_it]titolo[/lang_it][lang_pt]etc[/langpt] etc etc I have visualization problems. There’s a way to solve this?

Thanks everybody
