I have a rss feed for my demo blog here.
It passes the 'user' variable 'john' into the feed posts.
I need to add the 'user' variable to the link.
Note - I had to replace my domain with 'websiteurl' below as this site wouldn't let me post more than 1 link as new user
Please can someone tell me what I need to change in the function.php or feed.php files.
