RSS (Really Simple Syndication) is a method for websites to alert followers to new updates. This Wiki has an RSS feed located at https://wiki.irishdenetwork.org/Main/WebRss.
Many clients are available to make use of this service; details on configuring some popular clients are below.
Thunderbird is an email/chat/calendar client, similar to Evolution or MS Outlook. You can also use it to subscribe to RSS feeds, which could be an alternative to using the WebNotify service.
Go to the Edit menu, Account Settings, and Add Feed Account if you don't already have feeds configured.
Click through the dialogue boxes to set up a Feed account.
Select the Feed account, and go to Manage Subscriptions...
Paste the IDEN Wiki's RSS feed URL into the Feed URL box and click Add.
You can then click Verify or just go and open the feed in the main mail screen.
Each notification item appears as a message in the feed's "mailbox".
