> Other forums that I use allow me to request email notifications of replies to any thread that I have posted to or replied to. I use filters in my email client whenever I need that. > The forum does not need to know which posts I have read to do this: it only needs to know which threads I have posted or replied to, which can be found by a search. The forum software is discussed on the [fossil forum](https://fossil-scm.org/forum/) . Your patches might be considered, if processor and I/O load are not excessive.
