-[Moved to Suggestions]-
1) How was this discussed to clan war with them? Ambassador privileges/rights (the ability/right/rank to speak on behalf of/for JSO in such instances) is gained at the rank of Jedi/Sith Knight and even at this rank they must consult a Council member if Jedi or the Emperor if Sith. So I'm confused as to why you are telling me this and how this information was attained??
2) What mod does their server use? As lightsaber combat styles specifically are variable based upon the mod (modification) in play. JSO's server is running JA++ Mod (JA+ v2.6 B1)
3) If they are Hungarian and we are mostly American, who is hosting the server to TFFA on for this event? And with knowing this; I hope they (the Hungarian Clan) and you realize it is inevitable that one Clan (them or us) will be the more lagging bunch than the other due to localization (locational) ping differences? (Located on different parts of the map) - I don't mind switching the gametype to TFFA for the event and hosting it on JSO's server. But we are going to need THEM(their Leader(s)) to register accounts here on our forums and post in "Inform the Council" (as you did originally) proposing such an Clan War event and then we can discuss the matter further. If they are not very great with English, Google translator will help, but I don't know what we will do in-game in that respect if that's the case
