There are a few more from you part of the world on here--there is also a wonderful archive of posts about all kinds of signs and other things.
If you want to search the archives, the best way is to find the Google custom search box that says under it Oldgas.com search powered by Google (at the bottom or top of the page you are looking at). That way if you put the name of a sign you want more info on, you can look it up. Keep in mind that if you reply to an older post, some will point out to you that it is a much older post.
Or you can post your question directly into the general discussion forum. Pictures are a must if you have a question about a specific sign you have, and there are plenty of tutorials on how to post images.
Have fun!
