How to get around having a large amount of projects to get accomplished and not forgetting them?

Here at work i do many different things such as create web sites or IT work. Well at some points i ended up have a million and one things to do and had problems keeping track of them and insuring things got done properly and ON TIME.

What i finally broke down and did was created myself a "to-do" list of things that need done. Where i can add things to it as well as have other people in the company add things to it.

This process has been working out great because i can look at one page and see little comments just small things that remind me to look into something or remember about something that needed done. The best part that i like about it that i can easily look at everything and figure out what can be done fast and what needs done right this second.
