I have noticed that some of the projects in Pharo GSOC 2018 Ideas List are copied from last year's list. I've asked people who have been assigned as mentors to these projects and they told me that they will not be mentoring them this year.
I have created a pull request for removing two old projects that I found and discussed with mentors. But there's probably more.
I think that the list of ideas has to be thoroughly reviewed and old projects must be removed from it before students start applying for them.
Is there someone maintaining that list, who keeps track of all projects and knows which ones to remove?
