Well, the best way to get a nice JP party going is to start a PT yourself. Most JP wont refuse an invite if you're sure to send a tell as well. It's good to ask the following:
sumimasen, ima ojikan arimasuka? - Excuse me, do you have a moment?
isshou ni PT kumimasenka? - Would you like to put a party together, together? (Wow, my translations suck. Basically it's "do you want to join my PT?")
If they respond in hiragana/katakana/kanji, you can tell them:
Sumimasen, sore o yomenai. romaji de kaite kudasai. - I'm sorry, I can't read that. Please type in romaji (english letters).
It's not good to be too demanding of your party or anything like that, so I wouldn't suggest using this too much, as a lot of Japanese players may feel threatened at having to change how they need to communicate... but if you're really having that bad of a problem, you can as this:
eigo o hanasemasu ka? - Can you speak English?
eigo o ********* kudasai. - Please speak English.
Or, if you feel lucky, since you speak French, Une... ^^ I can almost guarantee Japanese people will know more English than French, but you never know!
furansugo o hanasemasu ka? - Can you speak French?
furansugo o ********* kudasai. - Please speak French.
As far as setting up a good comment goes, you could say (and I really suggest using the auto translator...):
(Food)=(Meat Mithkabobs[or whatever])
JP/EN PT ok (I don't speak any Japanese.)
iroiro na PT o sasotte kudasai. (Please invite me to a party with some variety.)
Now, I can't guarantee you'll get a JP PT all the time. But, well, luck to ya! If I'm on and you need translation help, just ask me. Verence and Ayvaen tend to do that a lot. >.>
