Hi -- I approve of the edits you are making, in fact they are very nice, but one small thing: you should not mark an edit as "minor" if it changes the meaning of the article. Basically the only edits that should be marked as minor are fixes for spelling, grammar, or format. Regards, and welcome to Wikipedia, Looie496 (talk) 21:54, 2 January 2009 (UTC)[reply]

Thanks for uploading File:Carolyn wood MI.jpg. You don't seem to have indicated the license status of the image. Wikipedia uses a set of image copyright tags to indicate this information; to add a tag to the image, select the appropriate tag from this list, click on this link, then click "Edit this page" and add the tag to the image's description. If there doesn't seem to be a suitable tag, the image is probably not appropriate for use on Wikipedia.

For help in choosing the correct tag, or for any other questions, leave a message on Wikipedia:Media copyright questions. Thank you for your cooperation. --ImageTaggingBot (talk) 16:06, 3 January 2009 (UTC)[reply]

The image you uploaded was an exact duplicate of an image you had uploaded a few seconds before. As the one uploaded before was already in use, I deleted the duplicate. Pretty standard practice per criteria for speedy deletion I1. J Milburn (talk) 13:19, 4 January 2009 (UTC)[reply]

Thank you for uploading File:TRP P.Americana retina.PDF. However, it currently is missing information on its copyright status. Wikipedia takes copyright very seriously. It may be deleted soon, unless we can determine the license and the source of the file. If you know this information, then you can add a copyright tag to the image description page.

If you have uploaded other files, consider checking that you have specified their license and tagged them, too. You can find a list of files you have uploaded by following this link.

If you have any questions, please feel free to ask them at the media copyright questions page. Thanks again for your cooperation. J Milburn (talk) 13:24, 4 January 2009 (UTC)[reply]

Hi there, I moved the section discussing the number of ions to the Wikiversity article, which is a good place to discuss and explain the topic in this way. The Wikipedia article needs to be written in an encyclopedic tone. Tim Vickers (talk) 17:20, 7 January 2009 (UTC)[reply]

Since no sources are cited, and the tone is personal and more like university coursework than an encyclopaedia, I'll move it to User talk:Rvfrolov/Sandbox so you can edit it into a form where it will belong in the article. I'd recommend just stating the bottom line and citing the source that supports this. The action potential article is supposed to give a general overview of the topic, and this does seem to me to have a bit too much detail. However, that is just my opinion, and I haven't seen your completed version. Tim Vickers (talk) 18:02, 7 January 2009 (UTC)[reply]
