I have read the FAQs and checked for similar issues: Yes

My site's URL (web address) is: www.sunembroideryscreenprinting.com

I have sitemap.htm file in my site which lists a description of each page with a link. Is it okay to also upload a sitemap.txt file to Google in Google's sitemap text file format?  In other words I'll have the htm page for human visitors and the txt page for Google? Thanks!
