Great to see (read) new faces around here. Fairly new here too, couple of months now. I fall under the category of "know just enough to be dangerous". I played way back when (1999) when Eq1 first came out. After a few years a friend of mine started to 6 box...manually. That means he had 6 computers and 6 mice and 6 KB's. He arranged 3 desks together to make a "U" and worked like a madman to get good at it. I used to watch him and just shake my head, knowing I would never be able to do that, but man I really liked the idea of having my OWN group at my disposal. Segway 18 years later, well for me anyways, we have software that not only doesn't require 6 computers but lets me control all 6 characters really well. All I have to do is learn a new "language". Kinda difficult for an old guy but I am getting there especially considering the steepness of the learning curve here.
Wait til the first time you take your 6 box team out for a spin, hehe, yeah. You go someplace. (anyplace really) and pull way too much by accident. Lol you should record it (I wish I did) so you can go back later and laugh at yourself. I was totally unprepared for the situation. It's mostly cause you are not used to controlling 6 characters. Takes awhile to learn how to do that, let alone the whole concept of a group mentality and not just 1 character. You'll learn lol and die. Remember the old saying. "You ain't trying if you ain't dying" lol.
Oh and check out some of the posts on these forums about ISBoxer, might answer some of your questions about the multiple windows open at the same time. ISB has another subscription that costs $15 for 3 months but I think it is worth it. To each, their own.
Welcome to the club.
