I’ve contacted this member to see what they would like to change their username to.

For future reference, username changes on the WGA website can only be performed by a webmaster (similar to the policy on geocaching.com). It is a manual process for me to change someone’s username, and the degree of difficulty depends on what “systems” on the site they have touched. But normally it is not a big deal, so if anyone else needs a username change, please contact me directly or send your request to web wi geocaching com.
