I am looking to test calls to action for sign in for a community...
Thanks for reaching out to the community!
As already posted in the other thread, you can find a whole section about ideation and hypothesizing in our Knowledge Base.
Of course, if you like to improve the new registrations for your community you could start testing the C2A buttons or the size and layout of the registration form. Further you could also try out different approaches (layout, text, imgaes, ... ) how to attrackt new visitors to sign up for the community.
I hope this helps!
