I'm not sure if there's a warning in the Jumpgate process, however it might be worthwhile to add something like a suggestion to create a copy of your pre-Jumpgate game, and convert it to Jumpgate, so that your original is relatively sacrosanct if you decide Jumpgate isn't for you. I did this, but only because I wasn't sure if Jumpgate might not lose something in translation, so I didn't want to risk it.
