In order to (1) address some issues that have cropped up with our forum's search system, (2) fully comply with our software's recommended settings and (3) maintain a more uniform decor across the board we will be modifying usernames (both login and display) to match the same rules as everyone who has registered since the 5.0 launch.
Simply put, if your username includes characters that are not letters, numbers or dashes it will have to be tweaked. Foreign characters, symbols, punctuation, etc. will have to go, which effects quite a lot of people. Note that if your current username includes a space no action needs to be taken but new usernames should not include spaces. If your username needs an update, please reply to this thread or send me a PM with a new one. Thank you everyone for your understanding.
