Job Search Organizer

Applying for jobs this year and keeping up with everything else, I opened a spreadsheet to keep track of my jobs. As I started creating the spreadsheet, I figured I could create it in Excel, and maybe create a section on my development server to organize my jobs through the web.

And the question that always comes up when I come across these tools of procrastination is that someone else has already done it. Question is where do I find it?

I figured creating a database where I could enter the job details, the date submitted, the status of my position search (apply for, submitted, followed up, scheduled interview), and other details. I would create a notes field where I could copy and paste info into and a page that would print out my results. I would a field that would alert me by email when interviews are scheduled or reminds me to follow-up on positions.

Agents
I have one agent/head-hunter or whatever you call it working with me through one company. I have job profiles through dozens of site and several job search queries bookmarked on Firefox that I run through daily. It all seems so overwhelming. I want one place, one location to do it all.

Agent Software? Head-hunter software? Do I even need it?
