Just a minute ago I wanted to make a short issue, and so I had to 
register. To do this, I was asked for the following fields:

Name 
Login Name	
Login Password	
Confirm Password	
Phone	
Organisation	
E-mail address	
Alternate E-mail addresses (One address per line)

Alongside a note, "highlighted fields are required", and of course, 
all fields were highlighted.

Why on earth do you need all this information from me?!

For example, why should I be required to have a phone to use the 
Roundup issue tracker for Roundup itself (RITRI)? Why would you call 
me?! Do you think people are going to give you real numbers anyway?

Pretty much everything but username, email and password should be 
optional in my opinion, probably not even asked for. How are they 
relevant? Please consider removing these, as they give the prospective 
user between lying to you or giving away private data for no good 
reason (in order to create an issue to improve your tool!)
