May be a dupe, but more up to date since that add-on doesn't work, etc.....
I just had a need for something like this today. Here's the scenario. Some potential clients are interested in how a certain program we have works. I used to put a whole bunch of pages together in Dreamweaver and post it in a URL, but now I want to simply put it in a thread in XF.
The potential clients may not be registered nor want to. It's not super-secret info, so the idea would be just to create the thread and have it behind a password.
As it stands, maybe I'll just create a single "client user" account and group to protect that particular form - so I guess it will work out anyway....although more complicated, because if the client does have an account on my forum they have to log out first...and then log in and then go to the URL.
It would be less steps to just give them a URL with one pw to it.
