How to view your posts in talk?
On the bug forums you can filter by your own posts, but here I haven't found any way to do this.
hum to view your posts you can search them here
You can also filter them with the hot, new, and top buttons. If your post is hot (many upvotes/comments) it will appear automatically because the talk is by default hot. But if your post isnt there, you can go to your profile, click posts, and scroll down to see all your posts.
But i think the best is to just search it, and you can filter it by searching in all, or just in ask, or just in tutorials, etc.
Happy coding and hope this helps! =)
