There's something wrong with the Tagging system...

[tk9780]

Tag? Sorry do you mean the tag that you added with your characters name [RMH] Mr Smith or the Freelancer IFF tag colour coded Green Friendly, White Neutral, and Red adversary, or the ID you purchase and fit in the ships hull? Because at the end of the day the first two within Discovery RP have no impact want so ever, its the Discovery ID tag fitted in the ships hull which indicates your RP allegiances.
The name tag been displayed incorrectly or not at all have more to do with server lag than where you got your copy of Freelancer. So in all its always best to check the other players Disc ID tag and not go by either the freelancer IFF indicator, or any indications within their character name tag.
Although it would be nice if players could be trusted to include a tag with their characters name that matches the Discovery ID been carried, but this would be like trusting players to keep their Rep in line with Disco ID allegiances.
