Is there a function within Silverstripe that does it or does it still need to be developed? (If it hasn't been done i'll do it.)
That provides a RSS Feed for all comments where as
yoursite.com/PageComment/rss/1 provides a RSS Feed of the page with ID of 1.
To make this more clear im planning on making a edit to the default theme which when you enable comments - down the bottom with the comments it has "RSS Feed for this Page" or something like that, Im going to add a "All Pages" link or similar to make this feature a bit more clear
You guys think of everything don't you! Choice
