I'm maintaining a WP plugin which is in the W.org repository. I have noticed that there is now a new plugin support forum page for each plugin (like this one for podPress: http://wordpress.org/support/plugin/podpress). It seems that there is also a new RSS feed for the posts on this page.
I have always used the tag page (http://wordpress.org/tags/podpress) as the support page and followed the RSS feed of the posts with the tag of the plugin e.g. http://wordpress.org/support/rss/tags/podpress.
On the new support page is a form which does not set the tag of the plugin automatically (like on the tag page) and some users don't set the tag manually. This leads to the problem that some of the posts on the new support page don't show up in the RSS feed of posts with the tag. That is why I have almost mist 3 requests for help in the last 2 weeks.
I have subscribed now also to the new feed (http://wordpress.org/support/rss/plugin/podpress).
But I think it would be still a good idea to set the plugin name as a tag automatically in the form on the new plugin support page.
