Is it possible to have one nether portal for all words?

I run a bukkit minecraft server with Multiverse and I was wondering if it's possible to just use one nether for all the worlds, so no matter what world the player is on they always will go to the same nether, but at different locations of course.

How to make a great business name with steps?

I have been having some trouble coming up with a good business name. My business will have a YouTube, with many different channels from news to how to's. We will also make websites for people and own a hopefully-large Minecraft server. How would I find a good name for the company?

How much ram for a basic minecraft server?

Basic vanilla server with few plugins (mostly necessities like world edit and anti lag plugins) and just about 5 people, how much ram should I use? Would 2GB be ok or should I use 4?

Good teamwork video games?

Kinda tired of playing alone, but so far whenever I find a mutiplayer game it's all about being the best, social interaction, or has a small amount of people. I want to work together with other people to achieve things. I want to feel like everyone matters, that it's a matter of skill and abilities rather then numbers.

A few games I've tried

WOW: Based around number of people, you need x amount of DPS, a few healers, and a couple tanks. Or it's a 10v10 battle to the death. It doesn't matter who those people are, as long as they have good gear. You have to optimise yourself and use specific attacks in a specific order, or you can't play with them.

TF2: Everyone seems to be focused on personal glory rather then objectives, and apparently I'm not allowed to be in the places that actually have teamwork since everyone there seems to be an elitist donkey.

Portal 2: Too short

L4D2: I felt like the teamwork was forced. You are only required to help people because the game mechanics force you to. Beyond that, more personal glory.

Minecraft: On big servers it's been all about PVP, building the best house, running off on your own to do stuff, or furthering your youtube channel. I feel like a number, and that I'm unwelcome, or unnoticed. Small servers I feel like I can relax, help people and what not, but they either die, escalate into large servers where I'm forgotten, or switch off into something else.
