I am not using VSD so have no knowledge of it, can you give a very brief description of what the difference is between RLM and RSD will be please? Are we talking about more control with RLM?
RSD will include almost everything you wish RLM did. Such as the ability to add images to the program itself. The ability to insert your own HTML, similar to how it is done in VSD.
I like to describe it like this:
If RLM were Bruce Banner then RSD is Bruce Banner angry. It is well worth the wait.
