Changing usernames is possible by emailing or messaging an admin with the desired new username. The topic frequently resurfaces, suggesting a need for clearer guidelines or warnings during the sign-up process. Some users propose reinstating an FAQ link or adding information to the forum library to assist new members. Despite the recurring discussions, username change requests are infrequent, averaging about one per quarter, and are managed effectively by the admins. Overall, enhancing communication about username policies could improve user experience.
