The Hall County school system has upgraded its website in an effort to improve its digital presence in the community, especially for those with smartphones. “What we’ve learned from the industry and our stakeholders is we need to have a mobile presence that is very simple and focused on addressing the most important things that our community, parents and students need to have on the fly,” said Aaron Turpin, executive director for technology. Turpin discussed the Web upgrade at the Hall County Board of Education’s meeting Monday night, with board members following along on their phones.
