RapidWeaver Classic doesn’t come with a built-in Stacks like system. If you purchased the Stacks plugin in the past you can try grabbing your license key from their order lookup system here. If you can’t find your old license key there we have an FAQ here on how you can reach YourHead Software directly.
So Kuler Solutions isn’t around anymore.
@yabdab is still around, but I don’t know about that stack you are asking about. You can still contact them though and they can let you know about that stack.
Can’t recall designertable or ratingssmall just from the name, perhaps someone else here does. Can you see any information that might point to who made those?
From some of the names of those stacks, it looks like you are looking for a Table stack, a Ratings stack, and a Comments stack, is that right?
