Reading the newsletter if sounds like the automated process is first going to try and fix role variables for us if the role is the subject of the sentence. Is there a way to opt out of this automatic update if we are happy with our [R:rolename] sentences and don't want to change to the new [S:rolename] variables. I can see where I will have to edit a lot of sentences back to the [R:rolename] otherwise.
Other than that, I am thrilled with this new feature. It sounds just like what we have been asking for for a long time and I can't wait to use it.
