Need a solution to allow users to login from my splash page

Hello,

how can i add the thin, clean buddypress menu (my account, dashboard, notifications) to my custom homepage/splashpage?

Heres my issue:

When someone creates a sub-site, they always get directed to my splash page, and the only way to see the login area is if they click "blog". Trying to not recreate the splashpage but simply add the clean buddypress stuff that's on the top of the screen if possible.

I've seen where you can change the wordpress code, but looking for a way to possibly add to my splash page so that I wont have to remember the code when/if there are updates.

Thanks in advance!
