!Friendica Support - I'm trying to add the Atom 1.0 feed
civicrm.stackexchange.com/feed… to my contacts - Its produced by Stackexchange so I thought it would be fairly straightforward but for some reason its not recongised - W3C Feed Validation service says its valid - validator.w3.org/feed/check.cg… - is it as simple as the fact that the URL doesn't end in .rss?
