Meetup Venues allows you to list Meetup.com events associated to a venue. This plugin is useful for the venue’s 
website to display what is going on at their venue.
A caveat to this plugin; when groups/users post events they do not always use the existing venue. This results in there 
being more than one venue listed per real physical location. You may need to use a comma deliminated list for the 
venue_id attribute.

Meetup.com Venues

This plugin allows you to list Meetup.com events associated to a venue.

For use with a <a href="http://meetup.com" rel="nofollow ugc">Meetup.com</a> group.
This plugin creates two widgets: one a list of events from a meetup group (by ID or URL name, for multiple groups use IDs); the other shows details about single event (by ID) with a link to RSVP – using OAuth if keys are specified, otherwise just a link to the event on meetup.com. Does require at least an API key (which it asks for on the settings page).

Meetup Widgets

Adds widgets displaying information from a meetup.com group.
