Hello, I'm MarkH21. I noticed that you made a comment on the page Wikipedia:Articles for deletion/Word-representable graph that didn't seem very civil, so it has been removed. Wikipedia is built on collaboration, so it's one of our core principles to interact with one another in a polite and respectful manner. If you have any questions, you can leave me a message on my talk page. Thank you. — MarkH₂₁ ^talk 03:49, 20 April 2020 (UTC) reply
