If you want any help maintaining this, I have about a decade of web design experience.
Also, if you want an alternative phpbb theme that is a bit easier to read, check out Ardota Black on the phpBB official styles page. I'd shoot you a link, but you have new member outside links disabled.
You can edit the colors as well to keep the red and black look. I like to highlight the accents an orange if red is the base color. Looks clean and easy to use.
