This also harks back to the altercation I had w/ TT some time ago.
His KNF-tagged vessel was acting within RP, conducting raids into Bretonian space. At the time, thanks to "off the record" negotiations, our Faction had an understanding (correct me if wrong, Madam deLuna or Adm. Firebird); that SF/KNF engagements would be limited to the Taus. Now, as this was not written anywhere on the boards or in Faction status; it was unreasonable of me to expect Tank's character to have knowledge of said "understanding". (Also, things may have changed yet again.. need that bloody deuterium...)
I suppose the moral of the story is that communication between similarly aligned players is always a good idea. We value our "pseudo members", the KSP, KTA, even our two KND brothers. If there's ever a question as to how to proceed in a given situation, hopefully a consensus can be reached through comms before misunderstandings occur.
