Thanks John. I haven't decided whether or not I want a unified feed. I finally got it working only by making up a blogger blog, then copying the html from there. I have no idea what was wrong with it. Still looks not very good, but I'll live with it until I have more time.
I remember from wikifray that at one time we had a feed that would post anything that anybody tagged wikifray in, I think, delicious. Do you remember how that worked? What I'm trying to do here is experiment with different things to see what might work best in a classroom (well, virtual classroom) setting.
Thanks for your help. Now if I can just get feedburner to send e-mails, I'll be happy.
WDJMBD? -- can that be hooked up to the bat signal? ^^^WDJMGD^^^
