“My browser” is just the particular browser I am using to access this discussion board. Since you are probably using a different one, it’s possible that the search button looks a little different. AT the top of this window I see a series of tabs/words that start with “HOME,” “FORUMS,” “MEMBERS,” ... “SHOP,” “DONATIONS,” and then the little search/magnifying glass icon. That’s the search button. “Search Member” is a different thing.
