..making random passwords is easy...simple hit the keyboard with a glove...then add a few *(&^% in between the letters, capitalize one and viola! random password...like this:
ru4;-w9bjq20...now add the *&^...for: r*u4;-&wbJq20 ....nice and random....
not hard at all...though I do like using the other characters and as the OP says, wishes that the master account would indeed allow them (I had fun when they changed over to the new system what, 4 years ago and my old password had symbols--and was 16 characters long--yepo had fun getting a new password for that one

)
any time they improve the security, even by just allowing symbols, its a good thing and I believe the OP was just expressing his wishes that they would indeed add this to theirs.
