Hi @/all , I have created a kind of roadmap - a list of areas to work on over the upcoming months in the Open Event project. Please have a look at the issue here fossasia/ and below.

The list of to dos and missing features for the Open Event project. Going through the list could be helpful for any developer who is interested in joining the project as well as for students interested to participate in GSoC.

Maintain and Administer System

  • Maintain system
  • Ensure it runs
  • Move files to "volumes" instead of hosting them on Linux system
  • Ensure automatic deployments work
    • a) master to
    • b) dev branch to (for testing purposes)


  • Fix reported bugs of system

@uds5501 Sounds great.
@/all We often see messages of people who say they are interested to join the project and contribute. Also many are interested in GSoC. Rather than writing a huge proposal we always recommend to contribute to the project to show their dedication. If you would like to join, please start learning about the system by solving some bugs and help to bring the project forward. Thank you!

You are using pip version 8.1.1, however version 18.1 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.
This is the error, any idea how to get past this?
