Heyo. You can customize your signature by clicking the "my preferences" link on the upper right of this page. The "Signature" field is on the first page. You may want to use something like this: "[[User talk:PTFE|Polytetrafluoroethylene]]", which will look like this: "Polytetrafluoroethylene 23:18, 6 October 2007 (UTC)". The timestamp is added automatically by the software. Let me know if you have any questions. Cheers, ➪HiDrNick! 23:18, 6 October 2007 (UTC)[reply]
I also would like to welcome you to Wikipedia. The articles you were talking about on "precision industrial spheres" under your old user name would be a valuable contribution. In my opinion, Wikipedia's coverage of engineering and industrial topics is not all that thorough. You might possibly want to make yourself a user page. You can do that by clicking on the tab that says "PTFE" and writing something. Cardamon06:40, 7 October 2007 (UTC)[reply]
