I'll join. It'll give me a reason to study some slavic langs.

Also, you say "The sound changes may not be characteristic to any modern Slavic Language (or any language other than the three listed, for that matter)," but also say " Be reasonably mutually intelligible with at least one other language within its branch (East, West, South)." How is this so? I mean, if it's not just bad sound changes o3o.
