This means that there may be `n` proposals on the project ideas page, but CC may be only be allocated enough project slots to support `< n` projects. The number of project slots allocated to each GSoC organization varies by year.

Any code contributions are good for first purposes, contributions to CC repos also show a general interest in our work so they count for both.
