A form could do the job just as well, though?
What is an example of a form?
The templates - bits of actual meta wiki code that crunch numbers for you - can't be stressed enough. It's
hard to re-create a character sheet in text; it takes a long time and it's a huge deterrent to new players. Also, you've got the WotC specter on your back if you create something that's TOO good. What we have on the wiki is a delicate balance; it would have to be simpler than that to get everyone to move back, especially since we just moved. That said, even if something is complicated to set up, if you can set it up once and forget it we have lots of talented, dedicated people who know a thing or two about coding who are happy to help.
Also, to expand on what stonegod said: we need the ability for multiple people to be able to edit and "ok" the sheet AND to be able to have a "frozen" state once it is okayed. However, it still needs to be able to be changed even after frozen! Currently, this is handled extremely well by wikis thanks to their
edit history feature. Every time something is changed, a full change state is created: you will always know if something is different because the full edit history (back to page creation) is on display for all to see. We need that level of accountability and flexibility.
Re: Campaign stuff
This looks pretty cool to me! Although I don't know that it really gains much more than a forum thread already does. Especially since you'd still have to use a forum thread in conjunction, right?
The main usefulness seems to be having a link to a character sheet on hand at any time, along with cloud-based DM notes that the DM can keep track of - which is very nice for people like me who use multiple computers in a day. Neither of those are really earth-shaking, however. If you could throw in a battlemat feature on top of that, I am
sold.
Re: Dice
Can we make them smal- just kidding!

It WOULD be nice to have a special DM-only dice area that could also be revealed as necessary, however. And if dice rolls were shown in the "Topic Review" when you're replying.
Re: Aliases
Also cool! I'm also wondering what the max number would be (at least 5? 10?) and if the alias would also have a link to both the character sheet AND the normal options for someone posting. For example, I'm exceptionally lazy and if I want to write someone a PM, I'd rather just continue to be able to click their name in a thread and PM them instead of having to click through a few screens to get to it. Another cool thing would be if the alias had its own speech color that you could set yourself, and any time you used a [speech] tag or something similar, it used that color.
