5 Things To Know Today: July 12

Accio Potter: Unless you've avoided the Harry Potter series, you know what that spell means: "I summon Potter." And if you say it at 5:30 p.m. today at Marian J. Mohr Library, it'll work — the library hosts Potter Mania in advance of the release of the film Harry Potter and the Deathly Hallows: Part 2, which is set for July 15.

Build Your Web Traffic: The North Central Chamber of Commerce, in collaboration with the Rhode Island Secretary of State's office and the RI Economic Development Corporation, hosts a workshop called We Mean Business: Planting Seeds for High Website Traffic from noon to 2 p.m. today at the EDC's office on Iron Horse Way in Providence. Wonder if they'll mention listing your business on Patch.

School Board Meeting: The Johnston School Committee is scheduled to meet tonight at 7 p.m. at Ferri Middle School. Watch JohnstonPatch for coverage, including tonight's agenda and reports after the session.

Planning Board Session: Also tonight at 7 p.m., the Planning Board is set to meet and discuss projects and developments in town. Location is the senior center.

Stones Roll — And Rock: On this date in 1962, the Rolling Stones played their first public performance, at The Marquee Club in London. They'd go on to do absolutely nothing of any note.
