# Enable QA-Website module, Save configuration
# Enable IdeaTorrent module, Save configuration
# Note: you will see this message: "user warning: query: CREATE LANGUAGE plpgsql"

# Follow the rest at:
# http://www.ideatorrent.org/docs/en/installation.txt.html

# There will be no "Submit idea" link until you enable the QA-Website blocks
#   Left sidebar: "QA-Website module action block 2"
#   Header: "QA-Website module action block"
#   Disabled: "QA-Website top navigation bar"

# Before the idea shows up, it must be voted UP by two users, so you need to create a second user.
# (this can be lowered in /ideatorrent/ideatorrent_admin/)

# Install OpenID Selector - Follow instructions at http://drupal.org/project/openid_selector
# Enable "Attribute Exchange for OpenID" and "OpenID Selector Inline" modules.
# Then go to My Profile / OpenID Identities, and click on your desired provider.
# In User Settings (/admin/user/settings):
#   Un-check "Require e-mail verification when a visitor creates an account".
#   Check "Visitors can create accounts and no administrator approval is required"
# Disable password login / registration by commenting-out code from /var/www/modules/user/user.module:
#   user_login_block function: from $form['name'] to the end, leaving "return $form;" untouched
#   user_edit_form function: from "if (!$register) { $form['account']['pass']" to the end of the elseif block.
# To keep only one OpenID provider, comment-out the other ones in:
#   /var/www/sites/all/libraries/openid-selector/js/openid-en.js
