The question is, since some others have expressed they have no problem with things as is, does the community want to expand? If there is a serious need/desire to expand the player base... then I would humbly agree with the others who have said the chargen process needs to change. If there is no such need/desire, then... it is what it is.
For my part, expansion is not a goal, but it's not something necessarily to be avoided, either. We need some influx, since we're always losing people to burnout, loss of interest, lack of free time, interference from that pesky real life nonsense, and so forth. Without new people, we'll eventually trail off into inactivity. (*cough*LEW*cough*) Besides, there are lots of really cool, interesting people in the world, and I'm pretty sure not all of them have joined L4W yet.
But we can't afford to grow too quickly, either. Right now we have plenty of DMs for our player base, and we're (barely) keeping up with judging responsibilities. But if we got 50 new players tomorrow, well, that would be messy.
Would it be practical to port over the enworld wiki to wikia.com? Our current scheme may not be the easiest for new users, but it has a lot of benefits that have been pointed out by evilbob. I like the wiki.
I think it's time for something like this, yes. Someone (JNC?) made a test wiki over at wikia to try it out:
L4e test Wiki
Someone should try copying and pasting our templates over there, and a character sheet or two, just to see if it still works outside of enworld.
I'm not thinking about wikia with a mind towards changing our character sheets or improving reviewability or anything like that (so this is a bit off-topic), just thinking of trying to preserve the information content of the wiki for when Morrus gets around to shutting it off.
