"Allow sharing through social media?" – misleading label
Without going into the design / etc issues of the Help Spread the Word social media box at the bottom of event and contribution pages, the checkbox enabling and disabling it is a little confusing. Users could turn it on by mistake because they check a box asking them to "Allow sharing through social media?" of the event or contribution page in question.
Obviously everyone clicks yes to that. But in reality obviously any public page can be shared through social media - this checkbox neither enables nor blocks social sharing. Unless I'm badly mistaken, checking it simply adds Facebook/Twitter/LinkedIn share buttons and tracking code to the foot of the event or contribution page in a green box. It would be clearer to label this as "Add social media sharing button footer".
