Hi, the standard name chooser makes sure that the character '+', '@' are not used in the beginning of a name and '/' is never used. When asking the name chooser to choose a name for me, I thought it would normalize those characters away, giving me a usable name. Reading the interface, there is a distiction between checking a name (and giving an error) and choosing a name (create one, maybe with a given name to start from) that is valid. I'd consider this to be a bug and change the name chooser accordingly. What do people think?
