What's the next best thing to an IRL homeschooling buddy? Why, a whole board of imaginary forum friends! I have found tremendous support and tapped into a vast fount of homeschooling knowledge through my own experience on the SL Forum, and I highly recommend at least browsing a favorite forum or two from time to time as a reminder that you are not alone, your children are not weird and yes, everyone gets a little stir-crazy from time to time.
Here are a list of a few forums recommended by some of my imaginary friends. :-) (Curriculum-specific forums noted with ***)
Sonlight Forums***--limited access to the general public, full access with subscription or purchase
WinterPromise Forums***--full public access
Homeschool Spot--small Christian forum
The Homeschool Library--large, free access board
Homeschool World--various topics
Homeschool.com--mid-sized forum with a used curricula board
VegSource Talk & Swap--mega board!
Clearly, this is not an exhaustive list of the forums out there. But it should get you started. Whet your appetite ... and make some new friends!
