Hi - I'm Girth Summit, and administrator here. I noticed that since creating your account, all of your edits have been to add external links to dewesoft.com. Please take a look at WP:EL: links to a commercial website like that are not appropriate. Please don't add any more such links to our articles. Thank you.
