This may be an overall site-design question, re: all the SE sites.
I have a pal that spends more time on SO, but stops over here occasionally. I see lots of questions on DBA.se that I may not know the answer to, but I'm sure he would. Same for another pal who is an Oracle expert. It would be nice if there was some way to notify them of the question using the SE inbox as opposed to having to email or FB the question out. Is this possible?
