Help talk:Wiki University--Sandbox

Hello. Anyone there? This is newbie Tom. Got a problem with the "Finding all your sandbox pages" section. The Prefix finder does not appear to work, or it needs a more detailed description. In the Wiki search bar I typed and received "There were no results matching the query." Well.... there really is a folder out there... its name is User:Zenonarc/Sandbox/TestPage What's up?

I actually entered { { Special : PrefixIndex / User : Zenonarc }} (without the spaces)
