I think you will find it 'very' useful, it does take some time to find your way around FS but, feel free to ask questions about how to search and find things.
Bear in mind that, good though the subscription sites are, there is NO 'one size fits all' site that will give you the answers you are looking for. Reading posts and replies in these boards has helped me enormously over the years. Learning where and how to search is half the battle :-)
