Thanks for your post, but I'd like to offer some suggestions if you plan to become an active participant in the future. First, disclose some of your backgroud and experience so others can determine the amount of trust they can place in your posts. Second, when you do post, please try to make at least some attempt at a post that is relevant to the question posed. Third, perhaps you could help us understand your connection to the MLS-related website you included in your post and how that is relevant to trademarks. MLS listings and trademarks don't appear to go together very well.
Thanks again, and we welcome your input.
