Absolutely! But sometimes (for me, anyway) the language in official documents is ambiguous and it drives me nuts! Plus I love the human "conversation" we have here.
One question that I had/have that I couldn't find a direct answer to is regarding the end of the Mass. I believe the priest is supposed to say "Mass is ended. Go in peace to love and serve the Lord." Well, at the Mass I most often attend, the priest says "Mass is ended. Go in peace to love and serve the Lord and each other. May his light shine down upon you, May (and he goes on for about 5 more lines)" - so FR is great for things like that when you can't find an answer or the answer you find isn't clear. As an aside, I think the priest might be wrong in my parish because the Masses on EWTN do not end this way. Also, I saw bits and pieces of the 9-11 memorial Masses at St. Pat's in NY and at Our Lady's Cathedral in Washington yesterday... neither of the Cardinals closed the Mass with anything beyond "Mass is ended. Go in peace to love and serve the Lord."
I'm mindful of being too technical... I don't want to be the Catholic police, or something, so maybe I shouldn't be noticing stuff like this, I don't know.
There are different options. Sometimes our priest will sing the multiple dismissal prayers to which we answer a capella "Amen".
And then other time he or the Deacond uses the regular form in dismissing the congregation. I think it can vary church to church.
