Thanks, Paul
That CSS worked great. I changed the background to brown and it became transparent which is even better. But in retrospect, since only board members and volunteers will need to log in to access to certain lists, etc., the login method could be on a Volunteers page that solicits volunteers and has the login button.
I'll have to experiment with the top positions. There's two now: top1 and top2 that were there after installation of Helix and SPPB.
Thanks for the background suggestion; I'll try that out.
Gold and gore... Well, there's 'Smuggler Kelly', buried indigenous skulls, a murder in the channel, copper mine shares that were worthless, and the present day struggles with the County over ferry fares. All good ways to get our islanders interesed in the rest of our history.
