Here are a few links I can recommend. I'll add more in the future...

For philosophy students:

• How to write a philosophy paper - by James Pryor of Princeton, highly recommended for philosophy students.
• How to read a philosophy paper - also by James Pryor.
• The Stanford Encyclopedia of Philosophy - by far the best philosophy resource on the net, or anywhere else for that matter...
• David Chalmer's Web Site - excellent philosophy of mind site.
• The American Philosophical Association
• The Wisconsin Philosophical Association
• The Philosophical Gourmet
• The Society for Philosophy and Psychology (SPP)

A few of my favorite miscellaneous sites:

• The Hunger Site - give charity simply by clicking, at no further cost to you... no kidding.
• How's the weather on Mars today?
• Live webcam on Waikiki beach in Honolulu (my old home town) - something to ease the Wisconsin winter pain...
• Nice photo gallery site
• Cool stuff - highly recommended stuff by people who really know their stuff.
