Ok so my friend and I were discussing whether we'd put MPhys or PhD after our names when we finish our Masters/Doctorate. Personally I wouldn't want to put them after my name for anything other than professional things as it sounds a bit pompous (if thats the right word). No disrespect to people who do put legitimate things after their names if they take a lot of work to get.
Anyway we were wondering what the easiest way to get legitimate letters after your name or titles. I know about Dr Katze the cat that has PhDs and stuff but I'm not on about degree mills or whatever. Just thought it'd be quite an interesting thing see, because usually seeing lots of letters after someones name makes them seem more intelligent.
