Hi, Jax.
You give very little information so I am assuming you are referring to MS
Word.
You can't edit a template. You can delete it and then recreate it by saving
it as a Template in the "Save As" dialogue box.
As for the paper size, go to File//Page setup". It's prettywell self
explanatory from there.
Good lcuk
Ed
BTW It's 11.25 p.m here so, in case you respond with another question, I'll
not be back 'til the morning!! I'm sure plenty of others will still be
awake, though!
