Initially I had felt betrayed..... but that was based on the assumption that
Lhuna, Nilp, & SPM were all innocents, holding secrets from a fellow innocent (me

). More fool me, it never occurred to me until I "poofed", that just maybe
SPM was a werewolf after all, like I had hunched at the very beginning. Once I accepted that possibility, my view on "codes" changed. As SPM has said, they are no more a sure sign of honesty than anything else written in posts. Therefore, it's a moot issue. So I agree. Let 'em stand. Any innocents who get caught out by werewolves (who already know who's innocent anyway) have merely played into the werewolves' hands, and so much the worse for them.
A side issue for me had been, "why on earth would some innocents want to keep secrets from other innocents?" Here's my point: some of us, when innocents, ain't that great at reading codes, anagrams, and what-not. Any innocents who convey crucial information through codes, run the risk of some fellow innocents not getting it. But that doesn't mean there ought to be a rule against it. Either you're just playing around and it doesn't really matter, or you're running the risk of cutting off your nose to spite your face. So code away all you want, gifteds and innocents .... this particular player is not likely to figure it out when he's innocent, and will probably be clued in by fellow werewolves when he's a werewolf. So have at it.
