How To See My Questions

Click on your avatar in the upper right of this page, then select "My Subscriptions:"

This will bring up a list, but you may need to use Filters to change the view rom "Participated or "Following" to "Authored":

In-forum search can only go back so far—a few weeks or months. If you need to find older posts, use a site-delimited web search. Paste this search string into your favorited search engine:

site:discussions.apple.com "ChickenEgg"

That will limit the search to these forums and your user name.

NOTE: There is no space between "site:" and "discussions."
