Hi All, I'd like to nominate Heitor Matsui as a core for starlingx-config subproject. Heitor has been heavily involved for long period of time for the project, and provided valuable inputs to the starlingx-config subproject design and integration. In my opinion he will a great addition to the starlingx-config core team. Thanks, Bin
