Tonight, in their first meeting of 2014, Bulloch County Board of Education members are slated to consider a policy change limiting what school employees may include in the signature block of emails.Meeting at 6:30 p.m. at its headquarters on Williams Road, the board will also elect its chairman and vice chairman for the year and vote on the school calendar for 2014-15.The proposed email rule is a carryover from the controversy about teachers’ religious expression that occupied much of a regular meeting and special meeting in December. The restriction would apply only to the “.k12” email accounts supplied by the school system. The proposed new section in the board’s Internet Acceptable Use Policy asserts that these accounts are property of the school district and are not personal accounts.
