[lmm]

Japanese; you put it on the end of a statement to make it a question instead, e.g. "the server is up to date, ne?" to mean "is the server up to date?"

[bmn_]

That's incorrect, that interrogation particle (for making the question in your example) is か. ね is different.

[sosborn]

ね is the colloquial way of turning a statement into a question.
