gravatar images not working

[diingo]

Hull has a cache that overrides update to proper email and added user name.

Gilbert suggest pulling gravatar email using hashes. Something like this:

irb(main):001:0> h = {a:1, b:2}
=> {:a=>1, :b=>2}
irb(main):002:0> x = h[:asd]
=> nil
irb(main):003:0> x = h[:asd] || h[:a]
=> 1
irb(main):004:0> x
=> 1
** irb(main):005:0> x = h[:b] || h[:a] **
=> 2
irb(main):006:0> x
=> 2
irb(main):007:0>
