Can you make an Anonymous methods receive and return values?
Otherwise, they appear useful for void methods?

Thanks

of course an anonymous method can return a value:
delegate int DoIt();
DoIt d = delegate{ return 2;};
DoIt d1 = () => 12; //now using a lambda expression
int qpp;
qpp = d();

Yes:

Predicate<int> isEven = delegate(int i)
{ return i % 2 == 0; }; // C# 2.0
Predicate<int> isEven = i => i % 2 == 0; // C# 3.0

Console.WriteLine(isEven(4));
Console.WriteLine(isEven(5));

What's Predicate<int>, not familiar with Predicate class.

Thanks

I can't help but wonder how many puzzles you actually crack :-)

It's a predefined delegate. It is defined as :
public delegate bool Predicate<T>

very used in List operations like Find, FindFirst, etc

Simple questions like this can easily by answered by typing the following
into google

msdn predicate

Additionally, if you are not already familiar with it, you might be
interested in Reflector..
