http://www.linkplug.com/computers_and_internet/user_groups/LinkPlug! is about providing a directory of quality sites for world wide web users. Our goal is to list the best sites for a wide variety of topics giving our users the most relevant results for their searches. User groups are informal and their structure varies from group to group. Anyone can form their own group and set their own rules and schedule. LinkPlug presents groups, some of which offer free mailing lists, photo & file sharing, group calendars and more.
