Here are some examples of professions you might find in an agency, and how people might find exciting ways to contribute in the TYPO3 community:

• Marketers will expand their knowledge of TYPO3’s unique selling points.
• Salespeople will learn more about how TYPO3 creates value for the clients.
• Project managers can increase their understanding of solutions and best practices.

• Testers can share their experience and help the CMS meet their needs.
• Designers and UX professionals get a chance to make TYPO3 look and feel just right.
• Support teams can learn how others solve problems and the best ways to debug TYPO3.
• Accountants can increase transparency and optimize spending for the association.
