Here's a post I made on their community forum about this potential copy-off:
As you can plainly see, I was pretty upset at these guys. I know it might have sounded a little harsh, but I was really pissed that someone took phpBB's product.I MOD a bit for phpBB2 and I have a good understanding of its codebase and templates and its overall look. So, with that in mind, I have a question: isn't JForum just a copy of phpBB2 with some internal edits done? I notice some different things like new options and new arrangements of topics and forums and members and stuff, but the core look of JForum is identicle to phpBB2. JForum simply looks like a different phpBB2 style template - that's all. It looks like a copy-off of phpBB2 with some of phpBB3's features added in. The smilies are exactly the same as phpBB2, all of the images are exactly the same, the fonts and font colors are exactly the same, the layout is exactly the same, the registration page is exactly the same and I can go on and on and on about how JForum seems to be exactly the same as phpBB2. All I see are some small template changes/edits - nothing big.
So, can someone tell me how JForum is different than phpBB2? Does it use a different coding language or something? And don't tell me the little differences like the different looking form buttons, or the "My Bookmarks" page, or the different image backgrounds, because that isn't enough to convince me that JForum is totally different than phpBB2 and can be called "a separate forum from phpBB2."
Thanks and please let me know how this is different. I'm sorry if I'm wrong, but I am just sticking up for phpBB and the hard work that was put into making that forum solution.
Anyway, I want to ask your opinion on whether JForum is a copy-off of phpBB2 or not. Maybe JForum got a copyright that doesn't violate phpBB's rights, but it still angers me that they stole the whole subSilver template and a lot of the phpBB codebase.
Well, I just needed to let that anger out and ask you that one question. Thanks for understanding.
