Just a note that I’m selling some extra text links this month. I’ve dropped a few of the advertisers here because they were ugly, but I’m a pretty big fan of text links.
Normally I sell them for 50$/month, but I’m pretty tight for cash this month, so I’m selling them for $250/year.
PR7, good readerbase, great search engine placement. If you’re interested, drop me a line or just PayPal me the cash and include the link details to jeremy@ensight.org.
And, yes, if you buy for a year and want to change it later, that’s no problem at all. You’re buying “link space”.
Hell, someone could make a decent commission buying a half dozen spots and selling them, since you can often get 75$+/month for a PR7 link 
In addition, if anyone wants to advertise in the top-right dogear spot, I’ll take offers on that as well (and, really, on any ad spot on the site).
I hate it when things are tight, but grabbing a little extra advertising is way better than the alternatives!
