My email address is pretty long, and it gets eaten up by my description. Here's a screenshot of my Apple Stack Exchange profile...
The same thing happens on my Stack Overflow profile too. Could this get fixed somehow?
As Jarrod said, your email is unusually long. We have limited space in that area. Your email address is only visible to you and the mods. In rare cases where the mods need to contact you, the email address is already a link, so it won't affect accessibility.
