For everyone that is saying it is imposible they are wrong. TTG is a HTML forum, so it is obviously possible.

If you're serious, I fucking lol'd @ you.

Nothing is impossible, don't be foolish. He could make a login form and check the data against an XML file or other type of data storage, and do the same for registering and posting. Just have everything load from spreadsheets and markup documents and have the HTML files update data as required.

While this will be highly inefficient, it's plausible.

If he isn't going to use PHP, what makes you think he'll use XML?
But fair enough. It's possible without PHP, not possible without storing data somewhere.

Each member gets a manually created profile and they get a secret profile link.

How do you expect them to log in, post, or do anything else?
YOU would have to manually update everything, meaning you would have to go into your FTP every single time and add little edits every time someone wants to do anything..
