Is this the ChrisJones patch that is labeled "Not fully working / stalled" you are referring to? For 7.x, all we can really go back is RSS, from what I can tell ... it won't be until 8.x(?) that we will be able to get more accurate ... ? And even then, it will be a patch we have to add, not stuff that has been yet integrated into 8.x? ---- Marc G.
