I'm new at Dollars-bbs, but i realized that if someone use link "dollars-bbs.org/main/" he will enter dollars without using password. Is there a possibility to set our pages to navigate user to "dollars-bbs.org" if they weren't on this page before?

I don't think so, a member called shiro can help you more

The password on the landing page is nothing but folklore.
There is no other point to have it. That's why the server doesn't waste computation time to check that you typed it in.

But since we keep answering that question almost every week, I should make a thread about that.
