Searching the site for 'contributions' just gave me Bob's post for how to submit news items for consideration on the site. PMd him with the query about $$ contributions so perhaps he will post directly.
I certainly agree that supporting the media we use and enjoy is a good use of our money. As this site grows it will take more volunteer staff to run it, and certainly same or upgraded servers. I'm fuzzy on bandwidth but I know watching the Eagles nest in northwestern Iowa get pretty slow with 150,000 simultaneous views at any given time.
