Re: New Users Specify Password
_ck_ has developed an “instant password” plugin. The link is: https://bbpress.org/plugins/topic/instant-password/installation/
As he suggests you may want to install the “Human Test” plugin: https://bbpress.org/plugins/topic/human-test/
as the instant password will automatically log you in upon registering.
Create a folder titled my-plugins. Upload the plugin to the folder. Go to your bbpress admin interface and activate. You will now see a password field in your registration page.
Hope this helps!
