FeedDiscussion and Magpie Feeds (as updated) fail in 2.1.11
Both discussion populating plugin fail for different reasons. I mention Magpie feeds only because @vrijvlinder provided an updated version in this discussion (vanillaforums.org/discussion/29819/feeddiscussions-not-displaying-feeds-in-forum-discussion#latest) which reports different issues (which are resolved by now).
So here is what's I experience with FeedDiscussion: It does not import correctly feeds that originate from YouTube RSS (I guess it has to do with media content). Here is my feed: panel2.feed.informer.com/digests/ADMVGEABRL/feeder.rss
As a side note, I also observed that it conflicts with the polls plugins (imported discussions have their poll flag turned on).
It is important to note that the modified Magpie Feeds plugin (as modified by @vrijvlinder in the above mentioned discussion) imports the feeds correctly (which proves that there is nothing wrong with the feed). It however imports it into the wrong category (ignoring the category number indicated in the settings).
I'd appreciate a solution - anything that correctly populates feeds. ** We're trying to start a new closed forum with Vanilla and need to seed it with material we'll grab from RSS feeds.**
