"Email this user" is one of the amazing features which requires development. It helps in the communication, but currently, it doesn't support Wiki Markup or styling, which makes certain things difficult. (Personally, I do not like the plain text without any formatting.) There should be HTML support for the mails, I think.
Why is it required? There are three ways to communicate with other editors: talk page, IRC, and email. For some reasons, talk page is not always used. And thus, we rely on emails and IRC. There are some drawbacks of IRC, like what if the other editor is not available on IRC and thus, we need emails. But without the pin of formatting, we are not utilising 100% of the option, and without an option to hyperlink, things become difficult and the mail becomes inelegant.
Thoughts on this idea?
