RSS doubles

[Slack]

I use Mail in Mac OS (10.5) to retrieve the RSS feed at feed://www.gminsidenews.com/forums/external.php?type=RSS2. For the last month or so, it seems, I have been getting some of the threads twice. A few I have gotten three times. At first I would get them at the same time. Now they come as several hours apart with many threads in between. I use Mail to check other RSS feeds also, but GMi is the only one to do this. The others perform as expected. Could someone look into this and see if it can be fixed?

Here is a list of doubles I have gotten in the last few days:

Despite rumors, next Acura NSX won't be priced around $200k,

April U.S. sales show shift to smaller cars,

GM Europe to Invest Euro 9 Billion in Opel,

Fiat takes Zastava, GM empty-handed .
