 hello.comment=Hi @%s! I can help you index your Github-hosted website, provided that the repository name respects \
               the format ``owner.github.io`` (or has a ``gh-pages`` branch) and the command is given by the repo's owner.\n\n\
-              More on commands [here](http://charles.amihaiemil.com/doc.html#commands).
+              More on commands [here](http://charles.amihaiemil.com/doc.html#commands).\n\

 index.start.comment=@%s thank you for the command, the indexing process started just now. I will let you know of the outcome \
                shortly. In the meantime, you can check the logs [here](%s).
 
-unknown.comment=@%s sorry I do not understand you. See [this link](http://charles.amihaiemil.com/doc.html#commands) for more details.

 denied.commander.comment=@%s only the repository's owner can trigger such an action.\n\nIf the repository is under an organization \
                          you must be an active admin and **I must be a member** (this is because currently I cannot check your membership \
                          otherwise - see [here](https://developer.github.com/v3/orgs/members/#get-organization-membership)).
