I cannot for the life of me figure out how to find posts by a certain member. Ican find the member and even his empty hangar, but can't find the posts he has made on this site. Ihave not had issues with 10+ other forums Ihave visited, and am not computer illiterate, if someone could please help it would be great.

click on the member's name and then in the lower right corner of the profile tab ; click drop-down menu to find posts. "Show the last xx posts"

I do see what you are talking about and under forum sub profile I found it. Maybe he just has no posts?

I see this is in the marketplace support and I frequently get questions from members who have zero (forum) postings on an item that I'm selling. Maybe that is the case.

Another way to get there is to click the ratings tab and then click the profile tab again. It will change to reflect "View Recent Posts & Other Forum Details"
