Project/Task management: This place is to list all the different project management tools, web2.0 services, task lists, project trackers etc. These come in handy for those one off projects as well as small to medium projects. The following are the options if you don't like to own 'Microsoft Project'. Sometimes though you aren't managing a project, there arises a need where you want to create some representations like a schedule or a gantt chart or a milestone list - say, to just show the dependencies. In such cases, the following web based tools definitely come in handy for generating those quick professional diagrams. Gantter Gantter generates a quick Gantt chart given the task and start+end dates. So, instead of struggling to present this in Excel, you can as well use this option. Here is how the generated chart looks. Milestoneplanner Milestoneplanner is a flash based web application which gives the option of creating a timeline showing key deliverables. This might be just the one needed to complete your email - with a professional touch. 
The above solutions are actual project management tools and not personal information managers. Let me follow it up with task management tools followed by the GTD counterparts.
Organizing your life by managing all your Tasks/Lists :
Self/Personal organization starts with you, not with any tool. So, if you truly have the intention and think that you honestly need to, you would start doing things that get you organized. And, frankly, I am not that well organized and try not to becoming a 'control freak' myself. Still, I try to be enough organized to be on top of things that I need to be. Not missing a credit card payment, managing all your bills, replying to emails, target/delivery dates, meetings etc are things everyone should take care of 'on time'. And given below are the best places which allow you to do so. If you are not a geek and don't want to get too technical, choose the simplest tool you can from the ones below. The first step could be as simple as the one from http://www.pocketmod.com where you print off one sheet of paper and fold it to have all your important things listed or using simplegtd.com . And the important thing to keep in mind is that you are doing this for yourself and not to show off how complexly you are doing it. Try spending that little time to swift through the ones below and choose the one that appeals the most to you. And the most important thing is that 'Starting something is easy, the difficult part is completing it successfully, to YOUR satisfaction'.
Getting Things Done (GTD):
I had given an overview about GTD on the productivity page and here goes my collection of various tools/software I have collected over a span of 6 months. I have settled for Clearcontext's IMS (Information management system) to handle my 'information overload', as I am a predominant Outlook user. It is now seamlessly integrated into my work. I also tried Omea Pro which basically is an email management tool and that is under the email management section. And before you get into the actual list of sites, here is The actual GTD Book which is referred over and over on this page.
