like this line. this bit `:value => current_user.try(:email)` is tasty.
@jonlemmon suggested pulling this out into a helper method.
here's my guess at it but it might be wrong?

```ruby
= f.input :name, :input_html => suggest_user_name, label: "Your name"

def suggest_user_name
   { :value => current_user.try(:name) }
end
```
