If you like using a feed reader, here are two feeds you can watch to keep an eye on PTA forum activity:
-
https://forum.plaintextaccounting.org/latest.rss?order=created
all topics (without the replies) -
https://forum.plaintextaccounting.org/posts.rss?order=created
all posts (topics and replies)
Note the order parameter is needed, otherwise the feed order will be unstable and confuse your feed reader and you horribly.
Also: in general you can try adding .rss (or .json) to any site url.
More RSS notes:
A topic which is created in a private category and later moved to a public one, will appear in the feed at that time, but with its original (private) creation time as pubDate. This can cause some feed readers (eg bazqux) and the discourse matrix notifier to ignore it.
