i have no problem with it as a mod as long as a you don't do it all the time (or that it gets out of hand) and you have a specific purpose in mind (ie helping him) then im all game. would help if you put a translation of what you said and he said in English in spoilers or something make it easier for the readers and us mods who primarily all speak the common language english.
so if you want to have a conversation about say how the weather is, your favorite type of ice cream, or how awesome coh2 is
please do that in english, or pm him.
note: my opinion doesn't necessarily make it allowed or disallowed. As I don't own the site or make its rules, i just enforce them.
