See w:en:Wikipedia:Village pump (proposals)/Archive 113#Allow "suppressredirect" and "move-subpages" within userspace. There is consensus for the rights "supressredirect" and "move-subpages" to be avalible to all editors when moving pages around userspace. Not sure if this can be done by a simple configeration change, or if a change to MW needs to be made.
