Elaysia, I can only speak for myself when I tell you the following. I hope it helps you understand where I'm coming from with my mostly negative feelings about a mail system or a chat system in UO.
I'm 50 years old and married for 25+ years. My daughter and her two very young sons (5 and 2 years old) just recently moved home with us. I've also got a stepdaughter who's in her late 30s and a teenage granddaughter.
I've been well exposed to text messages and things like Facebook because of my kids and a few other friends. Unfortunately, they just don't really appeal to me. What smacks me in the face every time I log on Facebook is all the personal information some people post that I really don't wish to know. Do I want to know your baby's cranky today for the 25th day in a row? No, not really because I can't do anything to help you with the situation since you live clear across the country from me! Do I care that you can't decide what to make for dinner again today for the 300th day in a row? NO!!
I've had e-mail accounts, both personal and work-related, now for many years. I think the oldest account's creeping up on it's 20th anniversary. I've been using personal instant messaging systems for about five years now, but used work-related systems even before then.
I'm not sure how long I've been using voice mail. Seems like I remember getting that at work, oh gosh, I want to say back in about 1982 or 1983. And home answering machines have probably been around at least as long as that.
I've never played WoW. Have been invited to many times. However, it has no appeal for me, probably because of the huge number of people who currently play. After working for 25+ years in a huge corporation with over 35,000 employees, I had more than my fill of living life as a faceless number, thank you very much.
At this point in my life, I enjoy UO because it isn't so large that I ever feel lost within it. I have friends that I enjoy doing things with almost nightly. We stay connected via ICQ, Teamspeak, and even regular old e-mail once in a while. I have a wonderful time doing stuff with my guildmates and other friends I've made in UO, and wouldn't trade them for the world.
However, I also enjoy the fact that there is a lot of stuff in the game that I can do on my own, and then jump right out of and switch over to doing things as a group or even just as a pair or a trio. I love having that kind of flexibility. And I guess the fact that at least half the time I'm playing solo is probably a reflection of my (mostly) introverted personality type. I love interacting with other people, but mostly in measured and controlled doses. My family is who I wish to give myself to on a more complete basis. The grandkids can hog me for themselves for most of the day, as can my daughters and husband if they need to. But I truly have no desire to give myself unreservedly over to a bunch of people who are basically strangers to me. Nope, the walls stay up most of the time and I'm afraid that's not likely to ever change unless I undergo some kind of drastic personality change due to illness or injury.
Sorry this is long, but I thought maybe it might help you understand where I'm coming from when I try to explain why I would rarely find myself using a global chat system or mail system in UO. It would be far too intrusive for me to want to leave either one active for very long. And with all the other communication systems that already exist in my life, I really don't want the responsibility, however slight or unimportant it really is in the grander scheme of things, to keep monitoring either one. UO's "low-tech" approach to communication may be quirky and anachronistic to many; however, for me it is a welcome relief. Forcing me to have to endure watching an endless stream of chat flowing through the game window or journal would be just about as painful as having to play UO with a television set sitting behind me that no one ever turns off.
