You are misunderstanding, aardvark also is not multilanguage
.
It offers several languages files so your topsite is displayed in the language you select in admin, same as VisioList ( we are based on aardvark after all ).
Thats what the multilanguage refers to
I bet you talk about the mod flying around on aardvark which,
adds a select box on your rankings, now they see stuff like join page text, or menu item and what not in the language they selected.
BUT, no member description
Anyway in case that is enough for you, yes that possible in VisioList with a plugin also, quite easy actually.
Mentioning it again, member descriptions, which is most important for a visitor simply cant be translated, because its something saved in the database.
In case you want this plugin, i need you to understand this. Not that you expect something which you simply cant hope to ever get.
You also need to download all the language packs ( those you want to offer to visitor as choice ), like top50server said, because those obviously are needed.
Thats why i suggested google translate snippet
https://translate.google.com/manager/website/
With that the most important part gets translated, the member info. And as a side effect it translates the other stuff too
If you want the plugin, let me know, hope i explained it well enough
