Invite Anyone


Invite Anyone has two components:

1) The ability to invite members to the site by email. The plugin creates a tab on each member’s Profile page called “Send Invites”, which contains a form where users can invite outsiders to join the site. There is a field for a custom message. Also, inviters can optionally select any number of their groups, and when the invitee accepts the invitation he or she automatically receive invitations to join those groups.

The email invitation part of the plugin is customizable by the BP administrator, via Dashboard > BuddyPress > Invite Anyone.

2) By default, BuddyPress only allows group admins to invite their friends to groups. In some communities, you might want members to be able to invite non-friends to groups as well. This plugin allows you to do so, by populating the invitation checklist with the entire membership of the site, rather than just a friend list.

Because member lists can get very long and hard to navigate, this plugin adds a autosuggest search box to the Send Invites screen – the same one that appears on the Compose Message screen – which allows inviters to navigate directly to the members they want to invite.

Invite Anyone features optional integration with CloudSponge, a premium address book service, that allows your users to invite their friends to the site in a way that’s easy and fun. Enable it at Dashboard > BuddyPress > Invite Anyone.

* Serbo-Croatian:


  • Upload the directory ‘/invite-anyone/’ to your WP plugins directory and activate from the Dashboard of the main blog. Some users have reported problems when activating the plugin sitewide, so consider activating it on the BP blog only.
  • Configure the plugin at Dashboard > BuddyPress > Invite Anyone, where you can customize the default invitation message, determine which members are allowed to invite by email, and more. If you are running WordPress Multisite version 3.1 or greater, BuddyPress Dashboard panels are found in the Network Admin area.
  • If you are upgrading from a version of Invite Anyone older than 0.8, your data will be migrated from a custom database table (usually wp_bp_invite_anyone) to WordPress custom post types. After upgrading, if you are satisfied that the automatic migration has gone successfully, you can safely archive and remove the wp_bp_invite_anyone table from your database.

The actual form itself is useful and once you’ve set wordpress to use an smtp plugin, invites do show up in email inboxes. But the widget forces double-action, entering emails in the widget box, then again in the form as they are not passed to the form. It would be nice to have a shortcode directly to the form, so that I could make my own sidebar text box using the shortcode to encourage members to invite their friends. I’d rather the sidebar go directly to the form, than force users to enter emails twice.

it does what it says. the only problem is it sends an email with Wordpress username. wordspress@yourdomain I could not find how to change this email address so that it represents the site.
