The most popular map is a square. One base is bottom left, other is top right. There's 3 "lanes", top mid and bottom, which are paths to the other base. Along those paths are several turrets, which you pretty much have to destroy on the way to their base. Each lane has minions spawned, which are weak enemies that walk a straight path to the enemy base. Since they come in large numbers, once you've led them to a tower(turret), you're safe to attack it while it targets the minions. The goal is to get past all the turrets and destroy their "Nexus", the power source at their base.
You get 5 players per team, usually consisting of at least one of each playstyle. Carry, AP(mage-esque), support, jungle, whatever else. Tank maybe. Junglers generally play in the jungle, the area between lanes, which have some boss monsters that grant buffs when killed.
There's a few other maps(/game modes) but that's the main one.

But feel free to look it up yourself, I'm a complete noob to LoL.

All the commands are going to be removed at the same time anyways.
Anyways, I think ::stuck sounds less tempting. And a timer is useless. I can run out to the wildy, mine runite and tele back with a timer.(Just an example)
Making it work twice a day is lenient enough, not enough to be abused. And again if you get stuck more than that, you're doing something weird.

I had the most fun in Runescape during 2007. I think ~December of 2006 is the best goal here.

"The Capes of Accomplishment were formally released on 18 October 2006 after having been alluded to several times within the forums, after Jagex had received many complaints of dedicated high-levelled players not being able to have much to flaunt with. "

Honestly, I'm not getting a 99 if it means I have to go around saying "Hey guys, I got 99 smithing." It's not fair to the other non-combat skills if there's no skillcapes.
But again, this isn't even close to being a problem yet. I think we just shouldn't stop updating until we've got all of 2006.
