SQLite Forum

Cannot change my email settings
> 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.
