Contact Virus is probably the simplest and quickest tool which you would find to build your contact list for any event or meeting. Why Simple ? Coz it gives what is most required Name , Email, Mobile, Location and Gender !!!!. That should be more than enough for most of the events as email and mobile is what you will be requiring most of the time.

Online Contact List for Meetings

You get a unique URL which is to opened up by a shared key which you provide when you had created the list.Now you can pass this url  to all the people whom you want to invite for the event along with the key and url. Job done!!! Now you go and try it on the Contact Virus

Now this is simple. Sometimes we need something complex lists, lets say adding url and all. Any online and free tools you know ? Do suggest us!!

Update::: The only drawback I find  with this is there is no option to hide. So if its an open list there is high chance of getting spammed. At least there should be provision for hiding some fields like Mobile and Email.!!
