Some settings in SCLogin that will be pertinent:
* For the modal links - Login View Settings - Modal Popup and Modal Style - Text.
* When you do click the Login link, if the modal doesn't popup, then also look in the Module's Advanced section and try enabling the Load JQuery option.
Our template just has a module position in the top 'bar' area up there. In there, we've assigned 2 modules:
* Menu module - This is the 'main menu' shown up there
* SCLogin module - This is the login module
The you may need some minor styling to position it exactly as you'd like it.
I hope this helps to get you started, but let me know if you run into any troubles.
Thanks
