I made a few strips, but one of them got messed up due to a bad page refresh, and it's marring my little collection. I don't see a "delete" button. Is there anything I can do?

As far as I'm aware only Donors have the ability to delete or edit their own comics after publishing. I could be wrong however and if that's the case I'm sure someone here will let you know. I think if it's major you can contact Brad and ask him to delete it for you.

...and if you liked that one, here's a link to my other stupid shit.

Nah, that's probably the deal. Might have to cough up some dough.
