Thank you!! I really hate putting all those periods in and I don't like the way it looks. But before I said something I wanted to be sure it was OK. The secretary is a real toughy!!!!
Thanks again!!!
Michelle is right that there is no prescribed right way, but I'd recommend PTO, no periods. It's how we do it in all magazine articles. It's easier on the eyes and it's easier every time you type (thousands of time per year).
As far as Strunk & White or the Manual of Style (if your secretary is a stickler), PTO is perfectly fine.
I may be incorrect here but in regards to PTO, it doesn't matter either way. I think that perhaps the issue may have come up because it's not correct to do P.T.A., it's PTA but since a PTO is ANY other organization then the acronym (even if you add periods) it wouldn't matter.
I was just wondering the correct way to write PTO. When the secretary proofs all papers she says the correct way is P.T.O. But I have not seen it written like that anywhere else.
Thanks for any input given!!!
