You may not be aware of this fact: Comcast employees must be authorized by the forum administrator in order to post in an official capacity. Employees have their names in RED and are designated as such.
If not authorized they can post here but cannot state they are employees. Nor can they allude to being employees.
You can contact the community manager here (Comcast Larry) about it;
