When I forget where I posted, I have few solutions :
•When I come back from a long period, I use "View new posts" at the top right of the forum and search for the posts where I left a message (with the black dot on the envelop icon).
•If it's for a message in the last 24H, there's a link at the bottom of the forum "see all the active posts from this past 24H", and I search for topics with a black dot on the envelop icon.
•At the top right, there's a "My assistant" where you can show your last 10 posts.
•If 10 is not enough, and few times a month, I go to my own Profile and select "Option > Find member's Posts", then I can check if I had any answers.
Though, a notification on the "My assistant" would be great instead of a Mail for each tracked topic reply, and own messages quotes like Rydian shown.
I don't check my mail very often, and sometime we want an answer on the same day, the mail notification is not needed anymore if we already checked the forum manually.
I think "My Assistant" would be a good place to store this kind of informations. (maybe add a number next to it for unreaded info "My Assistant (5)", which will be cleared when opened or when clicking a new button "clear notifications".
edit :
let's use Tempy points
Hey, I got 5 Tempy's !
