Remove Demo admin from Buddypress

Hi Piotr, you Awesome Awesome Wizard of web. With every ounce of respect there ever was.. How do i remove the Demo admin and the and the rest of the demo members from Buddypress. When i post, Piotr displays as author.

Hi,

Thank you Please login as an administrator and remove existing WordPress users. (Users -> All Users section)

Good morning, This is true. but i'm the only one left. and my post's author is being over written by the demo admin. i think maybe it has something to do with Buddypress -Thanks it's been corrected, i don't know how, but i'll chalk it up to Wizardry!

Side eye @Piotr, Awesome.
