When I registered my shiny new account, the new user form's password fields had size=25 and maxlength=100. Great! So I create and activate my account, then logout, to login and save my login info in 1Password. Hrmm - invalid sign-in? No, I copied/pasted my new random password correctly. Reset my password - this form has the password fields size=25 and maxlength=40 - that's quite a bit shorter now, and explains why the 50-character password did not save. So, I create a shorter one and go to login page. Invalid sign-in. Again? This form has the password field size=25 and maxlength=25. Ok, at least now I know what your real limit is, but I wasted the 30 minutes I had budgeted for skimming the site on this.
1) consistency is next to godliness
2) clearly stating password size limits is better than forcing me to use an inspector to try and figure out what you want
3) I realize this might be JForum's problem (I have heard Paul talk about making changes to the forum software on one or two podcast episodes), so if this isn't a bug in permies.com's JForum implementation, please file this bug with JForum
I never expect much from forum software - I'll try to spend some time talking about permaculture and not only griping about the site.
