As my blog has grown in popularity, I have seen an increasing number of people posting links to various commercial websites. For obvious reasons, PFStock's comment policy does not allow links to commercial websites (the only exception is for sponsors of PFStock where I have reviewed the link in question). Unauthorized comments to my blog will be deleted.
I hope that readers will adhere to this comment policy in the future. Note that this policy does not apply to links for bona fide PF blogs. However, I would prefer that PF bloggers contact me by Email (my address is in the sidebar) about a link exchange. If you qualify, you can have your blog listed for free.
