Hello there. It seems that you've, for some strange reason, stumbled upon my user page. Well, there's nothing much to say really – I'm just a guy from Croatia who has a thing for heavy metal music and well-written articles. I'm much more active on Croatian Wikipedia (where I'm also a sysop), but sometimes there comes a time when I correct and edit some minor mistakes or add needful information on this Wikipedia branch too. That's all, folks!
