I don't think you will likely get most to give away spots on any message board. Some may email you privately but I think most worked hard to find spots where they have had success or were given spots in confidence.
That said, this site is a great source of information and a quick key word search of the archives should give you all the answers for everything you need.
As a place to start if this hasn't been helpful is just drive out of Roberts Cove and you should see groups of boats in different places within minutes of coming out of the cove...start there. Keep your lines within 10 ft of the surface and your speed under 1 with the smelt and you'll catch fish.
Watch the lake in spring, it can get rough fast in that area of a wind picks up and be careful of floating debris this time of year when motoring out (don't want to hit a break away dock in the darkness).
