If it was possible in some way, it'd be nice if usergroups had old passwords attached to them. What I mean is that once you were put in the Class 2 riddler group you would no longer have to enter in passwords for phase 1-10 forums. Once you became a class 3 riddler you'd never have to enter passwords for phase 1-30 forums. Of course, once you become a class 4 riddler, you'd never have to enter a passwod for phase 1-60 forums, etc.
I'm pretty sure it's possible, but unfortunately I doubt it can be done with current tools and would need to be encoded
Having to re-enter the passwords for all the forums is becoming a slight pain for me as it seems the cookie has reached max size or something for both WR1 and WR2. I didn't have this problem until phase 61 for WR1, though it started more around phase 50 for WR2. In firefox I can still input the passwords and it accepts them/lets me enter the forum but if I click on any threads it says I don't have permission to view that topic. I have to then open the page in IE and input the password again in order to do so.
It would also help for when the cookies are accidently/intentionally deleted for some reason. Last night I had to re-enter 60 passwords for WR1, 70 for WR2, and 22 for WR3...a major pain in the a.
If this was implemented, people could also play from remote computers much easier as they wouldn't have to carry their password lists everywhere.
