In conjunction with my "Simple Bitcoin Guide," I have launched the "Bitcoin Better Business Bureau" to provide new Bitcoin users with a list of trusted sites. Sites with good standing in the community will be listed.
Users can also post complaints about a BBBB site. Should a complaint be posted about a site that you run, I encourage you to contact the plaintiff and post a comment on the BBBB site once you have resolved the issue. I will then contact the plaintiff to confirm that the issue has been resolved and make note adjacent to the site's listing.
