it’s not straightforward. It took me a while to figure it out, but I think this will work for you. Navigate to your profile then select the My Subscriptions tab. Then filter Recent Activity to Authored.
I’m attaching a screenshot for my profile. I filtered to participated because I don’t have any recently authored posts. It’s conceptually equivalent. Hope that helps!
Note: I’m not sure how ‘recent activity’ is defined. it’s probably not very long of a timeframe. I’ve tried other ways to search for my historical posts and replies within this forum without any success. If anyone knows how to find any threads you’ve participated in that falls outside of the recent activity timeframe, please advise. i’d be really interested to know.
