User talk:J-m.s

Hello, I'm 80.221.159.67. I noticed that you made a change to an article, List of TCP and UDP port numbers, but you didn't provide a reliable source. It's been removed and archived in the page history for now, but if you'd like to include a citation and re-add it, please do so! If you need guidance on referencing, please see the referencing for beginners tutorial, or if you think I made a mistake, you can leave me a message on my talk page. Note that your table legend syntax was also broken (miscolored). 80.221.159.67 (talk) 19:56, 20 September 2016 (UTC)
