It'd be very nice to have an "OpenACS Marketing" kind of thing, where those with marketing/graphics tallents could help us with ideas, logos, etc. in the promotion of the toolkit.
I put OpenACS and AOLserver logos in all my OpenACS sites, at the footer. If you look at http://fslc.usu.edu you'll see them.
For a PostgreSQL logo, submit a recipe at my PostgreSQL CookBook (http://www.brasileiro.net/postgres) and you get one absolutely free! 😊
Or you can grab it from http://www.brasileiro.net/postgres/cookbook/pg_powered_button4.gif.
