Content in your sandbox
Hi - I noticed that you have some very promotional text in your sandbox. Please see WP:PROMO - I want to help you avoid wasting any more of your time writing content like that, if it is put into an article it will be speedily deleted per WP:G11. If you would like to learn more about editing Wikipedia, you should take a look at WP:YFA. Cheers Girth Summit  (blether)  13:16, 19 April 2019 (UTC)
