Here are a couple more useful resources I wanted to share.
Just came across this helpful article on using web based event planning applications. They can be a great way to manage, organize and plan events online. The article gives several references of such applications, on which you can create events, schedules, track attendees, sell tickets, and lots more. Some of the services even allow you to set up a free website for your event.
Also, for those of you interested in business networking, I've mentioned LinkedIn before, which is a business social networking site. (You can view my LinkedIn profile HERE.) I've also just discovered and joined another similar site called Naymz. Here's my profile on Naymz.
These types of sites are a terrific way to build business connections, and to increase your web traffic if you market through a website.
