The link above leads to a discussion on ... Mercury. Please, don't run off. I know it is a "Do not suggest" element. However, while every previous suggestion of mercury has been futile because of the fact they could replace it with water or deuterium oxide, this suggestion is different. Throughout the first three pages or so, There is a detailed description of what mercury could be like, along with comparisons to water, deuterium oxide, and liquid rubidium. There are also very useful ways in which it could be used, also listed throughout the thread. I am sure I am posting in the wrong forum, however I felt this needed to be brought to attention. Also, please read the entire thread before responding, as coding issues have been discussed and possibly solved.

I just think it would be a handy element to have around, I really see a lot of really good uses.

@snowfire777 lol minor necro.

@snowfire777 well it could have been a month old rather than a few days.
