Making this post *public* for any and all to see/use/share...and *PLEASE DO, SHARE*!!! There is clearly a huge void when it comes to (some) people knowing this info., but are using names already-in-use anyway. These are THREE excellent start points to check name-use before using a business name. Check for yourself, share with business owners you know, or up-and-coming entrepeneurs planning their biz! Trust me...it will save you (and other biz owners) loads of headaches....and....help create a smarter public about these matters!!!
