How do I find my posts in this discussion board?

I don't know that the Hosts have ever given any specific information about how far back you can see posts. I thought it was a least a month but I'm just guessing.

There are two other ways of finding posts. First, try using Search (top of the page to the left of your avatar). Put your user name into the search box, and press return. Once the results appear, you can filter them by searching for only ones that you've authored, for example. The second method is to use your favorite internet search engine and restrict the search. The search string would look something like this:

site:apple.com Anthony Sbarro

It looks as if someone gave you the second solution when you asked this question before. ;-)

I'm not finding my previous post about this but using Internet Search is evidently better than Apple Search. Thank you.

I found it when I put your username into the forum's search.
