how do I see replies to my posts and also threads I have commented on?

[DD]

My memory is at times quite bad. and I don't always which thread I've used to post something. I checked the manual on reading unread post, but I can't for the life of me find the "Show unread replies to your posts" that's supposed to be near the header. So Can I get some advice on finding my posts and their comments and also conversations I'm participating in?

Header, right-hand corner, Updated Topics.

Hope this helps.
