Tip: Categorizing images
Thanks a lot for contributing to the Wikimedia Commons! Here's a tip to make your uploads more useful: Why not add some categories to describe them? This will help more people to find and use them.
1) If you're using the UploadWizard, you can add categories to each file when you describe it. Just click "more options" for the file and add the categories which make sense:
2) You can also pick the file from your list of uploads, edit the file description page, and manually add the category code at the end of the page.
- [[Category:Category name]]
For example, if you are uploading a diagram showing the orbits of comets, you add the following code:
- [[Category:Astronomical diagrams]]
When picking categories, try to choose a specific category ("Astronomical diagrams") over a generic one ("Illustrations"). Pro-tip: The CommonSense tool can help you find the best category for your image.

Mind reverting your revert to wikipedia's Phosphoric Acid?
the tetrahydroxylphosphonium ion is known. So please revert your edit.
- Firstly, why is this matter being raised on wikimedia commons, since the article is on the English language version of Wikipedia?
- Secondly, I removed a series of edits made by an IP user (18.104.22.168) who was blocked for three months just before those edits were made. Almost the same edits were also made by another IP user (22.214.171.124) on 15 January 2013 and they subsequently removed by another editor. Whilst, the first set of additions were unreferenced, the second set did have a reference to http://guweb2.gonzaga.edu/faculty/cronk/biochem/P-index.cfm?definition=phosphate but that web site did not provide verification of what is being claimed. The matter is quite simple to fix: you state that "tetrahydroxylphosphonium ion is known", provide a reliable source for it and after I've checked it I'll happily reinstate the material with the reliable reference attached to the statement.
