Feature Request

Is there a feature you would like to see in these pages that isn't here? Please and let me know what you would like to see. Many of the features currently in the site (the slider bar animation control, dynamically-sized pages, etc.) are the direct result of requests from users. Send your ideas to me and I will let you know what I can do. Thanks.


Molecule Request

Is there a molecule that I've missed? A favorite example... A really bizzare point group... All suggestions are welcome. Adding new molecules is pretty straightforward, so your suggestions and I'll try and add them to the list.

Bug squashing

Is something broken? Please let me know if something does not appear to be working. I test frequently using Internet Explorer, Firefox and Safari. Other less common browsers may not work properly.
