Facebook Assistant Administrator Wanted

by

I just got this email from Luke who’s been doing our Earthbag/natural building Facebook page. Please email me or leave a message if you can help.

Update: No more inquiries please. Already five people have written. I just realized we failed to mention this was a volunteer position that takes about 5-10 minutes per day. It’s just a matter of copying and pasting some text from this blog to facebook. Maybe some thought it was a regular job.

Owen, I’ve been really slacking on the facebook page. Since it’s creation in 2011, I’ve enjoyed posting things for your page so that others on facebook could enjoy it as well. My career & personal life have taken several turns since & leaves me unable to continue to post every day. I’m just not on facebook that much anymore anyway.
