Exactly. Happy to receive contributions, but the volume in some repositories (mainly the website) is just unmanageable right now. We will be applying temporary restrictions on repositories whenever activity seems to grow uncontrollably. If you encounter this, and you really want to submit something, just try again later.
I assume there are also some semi-automatic contributions, which makes everything unnecessarily more intense. Testing what makes most sense as regulation measures right now.
Thank you all that have contributed so far. Many contributions got merged already, and we certainly have way more contributors than we could possibly work with in the summer.
Reminder to everyone: For GSoC, 1-2 well-crafted contributions are enough for us to understand what we need to know. More contributions do not really make any difference.
