how do I now add RSS to my XOOPS site?
There are 2 RSS options you can add to your website: a reader and a tool to make RSS.
The module xhdl0 is a RSS reader if you want to put headlines from other websites on yours. You can download it here:http://www.peak.ne.jp/xoops/
On this Xoops.org website you'll find a couple of module to create a RSS feed from your site:https://xoops.org/modules/repository/viewcat.php?cid=84
