Outdated Hyperlinks in the Handbook

While going through the Handbook and mainly in the Glossary section, I have found the following problems requiring an update:

1. Hyperlink in the OSPR section of the Glossary leads to an inexistent place.
2. Hyperlink in the Points section of the Glossary leads to an inexistent place.
3. Hyperlink in the Task refinement / Agile poker section of the Glossary leads to an inexistent place.
