Somewhere on the right, beneath the Search field, there’s a link with “register”. Go over there, create an account(an automatic password will be sent to your mail address), then login.

You can then publish new material (whatever you think would be of interest as Startup Ressources for the Impatient Digerati), change your password, and view other contributors articles. Pretty simple, eh?  ;)
PS. Has anybody else noticed that WordPress rules? It even has Ajax for the back-end… :D
