I recently realized I don't have an organized list of the freelancers I know. When someone comes to me with a project that I can't accept for whatever reason, I usually try and think of someone who might be a good fit. But I don't have an actual list of people I can point them to. So I want to build a spreadsheet I can use to quickly grab some portfolio links from.
How do you handle this sort of thing? Do you have a list? If so, do you only add people you've met personally?
