Change the plugin as a whole! There are so many people who are having problems accessing their old plots because they changed their names, me included. I recommend a plugin called PlotSquared, which takes name changes into account and changes the plot according to the new name. It's also a much better and improved version of the current plugin we have. This way, we will avoid having threads in 'Help' complaining about Creative so that we can economize space on the forums.
So many people are posting that I'm deleting my previous posts so that I don't triple-post. Anyways, thank you!
I looked into the plugin and it looks reliable. The only flaw is that it's not yet updated to 1.9, but I support. I would love to get rid of the constant problems people have with name changes on creative.
