My client base is growing which requires me to have more professional looking websites. I found some very nice looking themes on themeforest however they always come with the logo theme brand at the top which I have a gut feeling cannot be removed. So for example something like the listify theme (http://themeforest.net/item/wordpress-directory-theme-listify/9602611) would I be able to remove the listify logo? I've tried googling it and there are no hits which may be due to private forums but I don't know. Anybody have experience in this? Thanks.
