Hi Daniel,

Your suggestion looks neat!  However,  I ran into trouble running it.

I got the error message:
"K:/_Utilities/Ruby_1.8.2-15/ruby/lib/ruby/site_ruby/1.8/rubygems/
custom_require.rb:27:in `gem_original_require': No such file to load
-- windows/system_info (LoadError)
	from K:/_Utilities/Ruby_1.8.2-15/ruby/lib/ruby/site_ruby/1.8/rubygems/
custom_require.rb:27:in `require'
	from GetUsername.rb:4
>Exit code: 1"

My line #4 was the require statement.

I tried "gem install windows", which yielded:
Could not find windows (> 0) in the repository

I tried "gem install windows/system_info", and got:
Could not find windows/system_info (> 0) in the repository

Would you please point out where I went wrong?

Thanks in Advance,
Richard
