When you make a hack thread, there is a field "add-on for threadid". When you type in a threadid, your hack shows up as an addon for the other hack. However, sometimes you just make a hack that belong together with the other hack by its purpose. For example, my invites hack and Michelle's e-steki referral stats hack are both about referrals. However, they are independent hacks and cannot be called "add-ons".

Besides, there is only one field, which means that only two threads can be linked.

So my point is, there should be a way to link hacks in a different way than "addon", and "addon" should be changed to "relevant hack(s)" or something. And, there should be a way to link one thread to as many other threads as required.
