I noticed the name of the person who wrote that link Sacrificial Anodes as being, "Erin B", could that be the sister of that fake idiot "Harriet B" whom we have read so much about on here Hartey?? ..Watch out for a posting on here from that other fake idiot "Starlite", trying to defend her "sister" ..
