LS Community URL

I recently made my LS Community URL into a tinyurl with a custom ending, so that I could easily remember and access it anywhere. However, when I changed my LS Comm URL to the tinyurl.com/XXX, it gave me a message saying it "appeared" invalid. Will it still work or will I have to change it back to the long one?

Please only use the original URL with FFXIAH.com
