Ideas

I was talking with a bunch of teenagers and the subject came up about how I keep track of my ideas for stories, or ideas for the story I'm currently working on. When I got home I began to wonder how many other authors have the same type of system I do?

1.) I have a few notebook strategically placed around the house, the biggest right beside my bed.
2.) I have a dry erase board in my office, but that is mainly my writing schedule( or what I wish it was).
3.) I'm working on two series that I'm working on. For these I have a poster board with sectioned by story and any important details listed under the right one.
4.) Whenever I come up with an interesting idea I jot it down, who knows when it might come in handy.

How many of you other authors out there have similar process for recording you random ideas?
