Linking up?

I need some help.  Tiffany and I want to link up some of our great projects so that more people can hear about them, but I dont know what I'm doing. Occasionally I will link up, but I never know what Im really doing. So here are my questions:


How do you keep track of who links up when and where?


 Do most people who put up a linky (like Tuesday Tutorial or something) let you link all week or just that day?


Do you put the buttons in your blog post, in your side bar, or on a separate links page?


Do you copy and past every single code or do you save them somewhere and know that you will go find all those places to link up?



Basically-- How do you stay organized with all the available links?



Thanks for all the tips! Hopefully I can get some insight and start linking up to your fabulous blogs!!!
