What language is this?

А и не желая да ограбвам хората от удоволствието да се запознаят с всеки един от тях сами.

Is that Bulgarian?

Thanks.

A friend of mine told me that it could be Bulgarian or Old slavic.

I'm waiting for an answer. Does this not make you curious? How can you be so obtuse?

Yeah, if you even looked around that same site you copied it from, you'd see a big "GoTo.bg" on the home page. I checked their forum too, looks like anyone who has given his/her location is indeed in Bulgaria, so I'd think it's safe to assume this is indeed bulgarian.
