Althea is a medical group in the UK,apparently.(Google) I took Althea as my forum name,back in 2004. I used the name of the heroine of a series of books I was reading at the time, The Liveship Traders by Robin Hobb. I was nervous about joining a forum and Althea Vestrit was a brave and resourceful woman who was afraid of nothing. She has served me well over the years.
