Robin Westberg has updated the pull request incrementally with one additional commit since the last revision:

  Updated after offline review
  
  The primary form of the command is now /issue add or /issue remove. The /solves command remains as an alias, and can
  continue to be used with the previous syntax, as the "add" word is optional.
