Not sure why all the concern over a 16 character password (its hardcoded in the software). I would says its unreasonable. Especially on a leisure forum. There is so much more to worry about than that. Unless you are using the same password everywhere and you just dont ever want to see it hacked. Which brings me to hacking. There are all sorts of hack and vulnerabilities that can get your information despite your 16+ character PW. Just ask Equifax! And thank them by the way that you most important information is now out in the wild. Then you have to worry about your own machine not being compromised. Keyboard loggers etc, Man in the Middle Attacks etc. There is so much more to worry about than +16 characters.
Better worry more that the site operator is keeping up with vulnerabilty patching of this site. Thats how your SSN(SIN), DOB and everything else Equifax has on you got out.
