To use the search feature, you have to be logged on. At the top of the page, just under the picture of the longrifle, there are several buttons, one of them is "Search". Click the Search button and the feature will open. Type in the word or words you want to search for. You can search for posts by a certain person or just use the default, which is *, which means everyone. You can also limit your search to certain boards within ALR or just use the default, which is all boards. I'm sure I'm forgetting something, but that ought to get ya started.
