I've seen other vBulletin forums use a green theme very like the one here on DP. Is this theme available for sale or download from somewhere? Thanks!
I think the theme itself is available for anyone, but digitalpoint's theme might have special features added by themselves. I've seen a blue vBulletin forum that looks like digitalpoint's forum.
Here's an example: http://forums.digitalpoint.com/showthread.php?t=2520288 I don't know anything about where to get those themes.
Thank you Wulkanen, that is actually the default theme of the script with a little customisation in the header - you can view the VB site here.
I don't. However, once you use any theme, whether it is on a blog or a forum, the site will to some extent "look like someone else's". As Wulkanen's posts above show, even using the same script as another site can make your site appear similar to other sites using the same script.
