Thank you for reporting this.
Naturally after moving to a new platform quite a few features might be missing. We will try to reinstate those that people are interested in. It might take some time to do so as we are really scarce on resources currently.
please note that all pages on the new website should have an RSS feed even though they have moved from previous version. To confirm feel free to add /rss to end of any url such as for example forums: https://focusfusion.org/forums/rss
