@skobkin @drq Yes, but it's more useful. Also you can mention authors in forwards, allowing continue this topic in new thread or subthread.
In same time, making "multi-reply-to" will allow connect two unconnected before threads. This really not useful and hard to implement. I even do not know how we should show such thread in UI/UX.
