Just after I posted last time appealing for help on Wikipedia, I got an email from Mark Horridge, who had contributed an article on Computable general equilibrium, one of the items I was asking about. There are still almost unlimited opportunities to contribute though. Here’s a list of stubs (short articles needing expansion). And there are lots of topics that don’t have an article at all.
There’s a bit of a learning curve in editing Wikipedia, but if you’d like to make a contribution without going through this, send me a few paras of text on a relevant topic and I’ll post it for you.
Also, a renewed call for help with Folding @Home. It’s very worthwhile and doesn’t seem to slow the computer down at all.

‘….contributed an article on Computable general equilibrium, one of the items I was asking about.’
Wow! There’s only the quick and the dead around here! I was almost finished mine.
Well, there’s no need to lose your contribution, which I imagine will be rather different from Mark’s. You can merge it in, or send to me and I’ll do it. That’s one of the many great things about Wikipedia.
Another stub gone – only a few thousand to go. Please critisise http://en.wikipedia.org/wiki/Available_for_sale
Crosslinks (or even redlinks) to “held to maturity” and “trading (asset status)” would be good. The topic is completely new to me, BTW.
This has been part of my bread and butter for the last 3 to 4 years. Will do the red links.
Accounting standards can be fun – that is why I enjoy commenting on economics.
