"Hi Lyes SEFIANE - just a note to express appreciation for the extra mile you went to help out with the Rogers network collection as the project quickly approaches a deadline. This bravo could also be for innovation due to you realizing the building blocks of the solution lay within NAVA, however the speed in which you turned around the result and re-worked parts of the tool was the most impressive. Enjoy your vacation, I think you ve earned it!"
