We allow links to personal blogs, major medical sites, and news sites. We also allow fitday. We made the rules against linking to other sites years ago, due to our no advertising/promotions policy. This helps ensure that we are all here for the same reason. We're considering disallowing any links entirely, since it's getting harder to say one link is fine while another link isn't.
I hope that helps
In the future, if you have a question about policy, please either post it in the Help forum or send us a PM. I only saw this question because someone else pointed it out to me. I'm not familiar with the post you said was deleted, I didn't see it. We'd like to make sure that everyones questions are answered, but it helps to send forum questions directly to us. Thanks
