Browser Plugin
TODO: there will be a plugin that adds an entry to your browser right click menu. That will open a new window with this app with discussions for the page you clicked on. For now ypu can do that manually and simply drag the address of the page you want to discuss into the link in the howler window.
Site Integration
You can integrate Howler as the comment system on any site of your own. One does not need a browser plugin to read the comments, but would will still need a howler account to post there. Click for an example.
Howler does not employ, nor intend to have a team of moderators, but anyone can flag any post to be held for review. Content that I am not legally obliged to remove and that does not contravene the terms of service from my hosting provider will be reenabled when I get round to it and cannot be flagged again unless the owner edits it. Comment moderation policy, includes content filter options so you can avoid seeing offensive content, but classification of content relies on the members and has not yet been completed.
