No disrespect intended to the mighty MoD (and it is nice to see you putting news onto RR) but this is the second time in the past week (that I have noticed) where you have created a thread where one already existed.
Convention is (where possible) not to reinvent the wheel but to add to existing posts rather than create identical ones. - just a suggestion.
RSS (Really Simple Syndication) articles are generated centrally and transmitted to several recipients (including websites) simultaneously. No one monitors receiving websites to see if the articles have already appeared. However, I don't know why there is such a delay between an article being published on the MOD/RN websites and being transmitted via RSS.
You can sign up to RSS feeds on your PC/mobile phone for things like real-time football commentaries where the content is updated automatically withut you having to refresh the display.
