something to keep in mind with "z" i personally like the z thing- just me but- it works best if the last letter is not an "e"
olivez > ok
bagz > best
with a ez you almost want to say
oli "vez"
see? or dont use the e if you can ditch it-
like i have: Pineapplz.com - on this one i ditched the e and it works great-
