When a group member sends an email to the group, the list server sends the email to the group members.
Listservs make it easy to have group discussions and share files using email. No more CC and Reply-all.
With online groups all listserv posts go to the group's page on the web, where you can search and follow conversations.
Group members can post messages and files from the web, and the post is sent out via email.
With OnlineGroups.net you have a site where you can start as many public, private and secret groups as you like.
You can control the name, domain, description and style of your site, and appoint group administrators.
