Implement Dynamic Sublists (dlists)
There is interest in having the ability in Mailman to support Dynamic Sublists possibly along the lines of the Systers implementation briefly described at https://wiki.list.org/DEV/Brief%20Technical%20Details.
The basic idea is to allow one to receive emails only for certain threads such as
- threads you started
- threads you replied to
- threads in which you were copied on a post
This issue is a placeholder for this idea. Discussion of requirements and possible implementation ideas is encouraged.
