You've added this code to the home page:
[[module ListUsers users="."]] Welcome %%name%% to the site bursting with character info, walkthroughs and much more on the Mario & Luigi series! Our site name stands for "MALE" because both Maro and Luigi are male characters, so please don't take any offence you female wikidot users. ;-) [[/module]]
Only logged-in users will see that. If you log out of your account that whole message will disappear and the first line on the page will be "The games we are currently focusing on are:"
Might be better to just have "welcome name" in the module, and the rest outside of it. Unfortunately that means it has to be on a separate line.
