User talk:63.152.72.116

Hello, I'm David Eppstein. I wanted to let you know that one or more of your recent contributions to Finite topological space have been undone because they did not appear constructive. If you would like to experiment, please use the sandbox. If you think a mistake was made, or if you have any questions, you can leave me a message on my talk page. Thanks.

Please do not add unreferenced or poorly referenced information, especially if controversial, to articles or any other page on Wikipedia about living (or recently deceased) persons, as you did to Steve Urkel. Thank you.
