Could you please-please-please get around enabling the system to let a person "subscribe" to all new discussions under any particular Discussion Forum category? There are probably dozens of questions every month I could try to contribute to if only I were alerted to them. (I rarely have time to manually hunt for them in a timely way by "surfing" web pages.)
I'm sure you can think of many reasons why it would be hard to do and why things seem fine as they are. I'd rather hear about "what it would take" to enable that ability, since sometimes the difficult becomes do-able after thinking through it (with compromises for less than 100% perfection or reliability). . . . For starters, please consider it for the New Questions inbox.
