By this, I mean I cannot edit my interests, 'basic info', or any of the like. How do I do this? Sorry, am new and very confused about trying to get used to this website. When I click on edit profile, it just lets me change the title of the boxes.

Aw hi, welcome little newbie :) Yea Subeta isn't very efficient with their labeling. If you go to Personal -> Dashboard -> Email, you can change your name and gender. (here)

I honestly have no idea how to change the interests section since I never used it. But! You can always add a Blank Section to your profile (Add New Section -> Blank Section) and write whatever you want about yourself

I hope that helps a little.

...OH, that's a little confusing! I see now, thank you so much!! ^__^

Yes, yes it did.
