which tags from XenTag or Xenforo default thread tags ? could be a permission i missed ? okay i see for registered user group [XenTag] Create new tag: [XenTag] Use staff-only tags: [XenTag] Watch tag: [XenTag] Edit tag: all are not set, so i guess create and watch tag need enabling ?
Yes, you need to add the permission for the required group (registered) to be able to create new tags. I only allow my members to add tags, and don't let them edit them (that's a moderator permission)
