I tried searching, but did not find. Is this the best place(or only) to get the rss feeds for the forum?
I think it is possible to create RSS feed for almost anything on discourse by adding .rss to the end of any url that you want to have a RSS feed of. For example, https://discourse.tt-rss.org/u/fox/activity/topics.rss fetches the topics created by fox, so that you can stay up-to-date on ttrss development & general announcements without having to go through individual bug reports, feature requests, questions, and so on that comes with the default RSS subscription to the forum. This is really a cool feature.
