Hello World!

Welcome and a comment
Welcome to Wikipedia. I hope that your experience is positive. To save everyone time and anxiety, I encourage you to consult our manual of style: Manual of Style/Chemistry. Some surprises for new-comers: our articles are written at a relatively high technical level, although there is always room for improvement in terms of clarity and content. The salient message for you is that we do not discuss routine safety issues. That information is widely available and more authoritatively so through what are known as MSDSs. For virtually any chemical compound, entire pages could be written on safety and tox themes, e.g. sensitivity, breathing issues, symptoms, occurrence in the workplace, etc etc. So we just dont go there ordinarily, again, as explained in the manual of style. We mainly discuss, well, chemistry and avoid generic safety stuff. Now for certain really special compound, like aflatoxin or cyanide, then we discuss the poison aspects but more from the scientific (vs advicey) perspective. Happy editing. --Smokefoot (talk) 04:09, 23 February 2013 (UTC)

File permission problem with File:Estrone Synthesis.gif
Thanks for uploading File:Estrone Synthesis.gif. I noticed that while you provided a valid copyright licensing tag, there is no proof that the creator of the file agreed to license it under the given license.

If you created this media entirely yourself but have previously published it elsewhere (especially online), please either
 * make a note permitting reuse under the CC-BY-SA or another acceptable free license (see this list) at the site of the original publication; or

You can find a sample permission letter here. If you take this step, add OTRS pending to the file description page to prevent premature deletion.

If you did not create it entirely yourself, please ask the person who created the file to take one of the two steps listed above, or if the owner of the file has already given their permission to you via email, please forward that email to permissions-en@wikimedia.org.
