I can't find the answer anywhere. I've been playing since 2011 but I've only ever bothered to make a few usernames with more than one capital letter. Most of them got deleted for being inactive for so long, so I only have one remaining. What I know for sure is that nonmembers could send gifts and were unable to change the color of items during this time period. The option for free chat was also available for nonmembers at this time.
