I use this a lot (more than 'Active Conversations' if I'm short of time and don't want to get distracted by other people's intriguing-looking threads ...) but the drawback is that by doing so I miss recent posts on threads that I took part in a while ago. E.g. the meet-ups threads for my area tend to go dormant for a while and then spring into life again, and I'd love them to pop up in my 'Threads I'm on' when this happens so that I don't miss anything. I know I could 'add a watch' to these threads, but basically I'd have to add a watch to every thread I contribute to in order to get what I'm looking for, and that does seem like more trouble than it's worth.
Is there another solution to this that I haven't thought of? Or could 'Threads I'm on' be extended to include ANY active threads I've contributed to, not just ones I've posted on recently??
