You all are already so busy, if you improve it too much, all that will happen is that more people will come and you will all be even busier.
But since you ask, I can't help noticing that the Geeks to Go freeware list appears to be much better than many of the other freeware lists maintained by other philanthropic help sites, but it is sort of buried.
Have you thought of putting links to it in more prominent and immediately visible places?
I would also suggest updating it, but the malware tsunami will have naturally pushed that task, along with a host of others, down the to-do list, and having recently been a victim - and an inexpressibly grateful recipient of aid and salvation - (I cannot thank or praise Essexboy enough for saving both my sanity and my new computer!) - I would not want anybody to be sitting there looking at that awful blue wallpaper, taskbar disabled and screen infested with the maddening popups caused by the ravages of the dreaded Lost.Golden.Bunny.Rabbit Malware FunPak while a person who could help them was updating the freeware list.
But I have also seen people asking how they can help, and there could be people who, while Malware Rescue might not be their area of expertise, might have a skill set that would be a good match for updating the freeware list.
You could even form a Task Force, and divide up the work of checking all the links to make sure they are still operative, and that the programs are still "clean" freeware (these days, sadly, that is going to be a concern for anybody with a freeware list), and in the case of recently added entries, have people (for safety, only Real Geeks with sandboxes) using different configurations of hardware and operating systems test them to make sure they do not make Vista users' heads explode, etc.
