On the topic of smote length: I tend to be one of those long-winded people, myself, who can make a reply take three or more lines. But this is very much dependant on the PC I'm playing at the time and what's going on around it. For instance, Areia tends to be very wordy in her speech, but another of my alts is most often more straight-to-the-point. Like Nearraba, I find it very enjoyable not just to know what a PC is saying, but also how it's saying it, what it is doing while it is speaking, and the like. However, when I'm in large and busy gatherings, or in very dangerous areas where mobs can pop up and eat you at any moment, I usually stick to SAYs and socials. That is all to say, I personally think it depends upon the individual player's preferences, the PC's unique mannerisms, and the situation at hand.
I'd also like to agree with Althasizor and others, regarding things like racial tolerance and so forth in FK. I've seen dwarven PCs on FK hanging around orcs and halforcs like they're best buds before, and that sort of thing kind of erks me. Players of halforc PCs who know Areia ICly will note she's not overly fond of them to say the least, and that's because, well, they're part orc. Neither FR nor the RL part of history on which it is very loosely based has much concept of equality between races, sexes, etc. (Have a look at how Kelemvor treated Midnight when they first met, if you happen to own the books). However, once or twice a PC of mine has been called out on using out-of-character knowledge or the like when, in fact, the PC had the IC background for holding such belief or what have you. So while we can make generalizations about what races hate what races, what classes are familiar with what knowledge, it's important to remember that there are instances where the PC might have sufficient reason to do what it's doing.
Something I've seen a few players doing, and something I've attempted on some of my alts with I feel enjoyable results, is actually showing us a PC's accent. Always, always try to keep good English in the actions in a smote, but I love reading not perfect English in a character's speech patterns. NOTE: This does not mean I think it's okay to eschew the use of punctuation, capitalization, etc. because you're lazy and don't think it's important (I'm one of those who will absolutely avoid characters whose players just don't want to be bothered to learn to write so that others can understand what's being presented), or that I would advocate a player's use of nonsense in a PC's speech just to be different. But there is a handful of PCs for whom this, in my opinion, adds so much depth to the PC and really helps me get a handle on what the PC is like. I'd encourage people with good IC reasons to try it out.
