Nice stuff as usual! Just a guess, but I am thinking that if you use the quotes with the suffix command, you don't need to have the underscore in there. The underscore (at least for the #lastname command) is only if you want to enter it without the quotes. I personally never use underscores for lastnames, because they will show up if you run MQ. Most server admins probably don't care about that, but I am just anal :P
Having prefix and suffix titles working is great! I have been waiting to see an option to add titles to a player's title window via quests or AAs, or whatever. Sounds like we are one step closer to having that! At least now we can set a title using quests. And, even if the title window never gets to be fully functional, you could still keep track of player title options by using quest globals, so they could change them at an NPC whenever they liked
