I understand that people want a link to their project they have worked hard on, but we cannot be a link collection.

OK, I am aware of that, but this is not a project of mine. The project is active now over 3 years and has also several programmers and sponsors. The current page includes projects that are no longer programmed (even the alpha). (And that already years)
A revision would be useful possibly.
