I haven't a problem either way, we are not gaining anything or loosing anything, Delights guildies should be safe in the knowledge that we are an honorable guild and don't go out of our way to hurt other players. I don't see a real need for change of tag at this moment but have nothing against it either.
After discussion in game, we decided to set you dark green. This means: we consider you a guild to be trusted, and won't attack harvesters or explorers in PK maps (however, if your members wander around in PK maps fully armed and armoured, all bets are off ). Also, there's no obligation on either side to help when requested, and the tag can de reset at any time.
On the other hand, your members can get access to our map to train, just ask a council member or in IG
