Could someone please point me to where this is explained or briefly tell me the purpose? Thanks much.
Thank you both for the explanation. I did try to understand the info in the original readme's for ETO but admit I did not clearly understand. The combo reply from you both helps alot. Reason...I do not want to screw up this excellent expansion and i see forum notes where others have 'done something wrong' and not have a big problem. Thanks again for you help on this question and for your work on this great ETO add-on.
