...What's the difference? Is this something geographically related, so that when a user in one country adds the QC project from the BOINC project list, the closest webpage opens, or what?

The first one is the main project, there is another one with continual, this is the testproject of 1. The other ones are only mirrors.

So if I wanted to describe the QC network, I should only bother mentioning the main one?

EDIT: I assume this is the other one you mentioned? http://www.ras.unam.mx/sensor/

no, this one http://qcn.stanford.edu/continual/

Okay, I'm probably still confused. What does each one do? I'm still not sure what the actual differences are.

Basically I just want to write a little something that advertises and describes a few BOINC projects, but I got stuck with QC because there are multiple pages.

So, if someone were to run QCN, should they run the default sensor, the continual, or both?

Also, slightly related, but what would be the cheapest cost of the equipment required to run QCN? I haven't seen anything overly cheap, myself, but I could just be looking in the wrong places. QCN and Radiation@Home are two projects I can't run because of the requirements.

That's all explained at http://qcn.stanford.edu/join-qcn/request-a-sensor. Those prices are of course excluding P&P and the cost of the additional hardware it needs to run on (such as a PC, etc.)

Hmm, that's rather steep for me, but I think I'll still use that information in case others might be interested.

You can get a free sensor if you're in an area of interest, that's how I got mine. There is also a version for Android devices, if you have one--it uses the onboard accelerometer.

Yes, I noticed that bit. I'm not in one, unfortunately. Still, useful bit of info if I want to try and expose the project to others.

So far, I've only seen the west coat of the US as an area of interest. Is there a list of areas? I assume these areas extend beyond North America as well, right?

EDIT: Looking back on this post, I think my usage of the word 'unfortunately' should be revised...

There are some special study areas where they ask for continuous data (versus only data when the software detects an event of significance) but I think the only international location where they're sending free sensors is Istanbul, Turkey. If you click on the Regional Program Get Started link there's a map and list of the locations, though the west coast is definitely emphasized as that's the location of the project headquarters (Stanford) and the most seismically active part of North America.

I found this on eBay. Cheap enough for me to buy it, and probably to buy one for someone else. What I'm unsure about is how QCN actually detects the sensor. Obviously I don't want to buy anything unless I have a guarantee that it will actually be compatible.

Anyone know?

I think your question would be best answered at the QCN forum.

Aye, I've asked, but since posting there, the site has gone down.

I killed QCN, it would seem...

The site is back, and you've had an answer from Les.
