Hypergeometric Series Acceleration Via the WZ method

\vskip.5cm\noindent
Based on the WZ method, some series acceleration 
formulas are given. These formulas allow us to 
write down an infinite family of parameterized 
identities from any given identity of WZ type.
 Further, this family, in the case of the Zeta 
function, gives rise to many accelerated 
expressions for $\zeta(3)$.
