Happy you’re giving Adapt a try. Hopefully you’ll enjoy it as much as we do.
If you’re a total newbie, you may be asking too much. Perhaps you should attempt to learn something about Adapt by trying to build parts of your vision first, then come back here (better yet, to the Technical forum) with specific questions focusing on your failed attempts.
I recommend that you first build out (to some degree) your main content pages. By that time, if searching the forums (I’d recommend you stick with the Technical forum) doesn’t give you clues about how to implement a start/launch page, posting there with a very specific question would be appropriate.
To learn how to use Adapt, please investigate the community website and the plugin browser, the authoring tool wiki, the framework wiki, and search the Technical forum (more productive than searching the Responsive Learning forum).
Also, are you the only one at Peak Pacific using Adapt? I’d think colleagues should be able to provide some basic mentoring on Adapt.
