No Roger - it is not routine - when the changes *may* be made on what ? One in a hundred? possibly (though I doubt it - probably much less occurance then that)

"routine" would be "as a matter of course", "frequent".

we currently have approximately 83,273 threads on the forum. Can you where even 1 tenth of 1% of those thread titles have been changed? Can you even come up with 1/1ooth of a percent of thread titles that you can show were changed without permission?
