Contact email address - a new CMS function

[c0mp0ser]

I noticed that the password is cleverly stored in the WCMS database. Wouldn't it be possible to save contact email address in a similar way, so that later on, using new additional WCMS function I could call it from database e.g. in contact form? Would it be possible to add this? It would be very useful but I don't know if it is possible to do it in a way that would be safe ...
