I mean Wedge, a fork of SMF is basically SMF with a different name minus a few minor features from what I have seen.

Ability to use colour, bold, italic, underline and arbitrary CSS for all user names based on their primary group
Notifications system
Ability to edit registration agreement from the admin panel without requiring file write access, and also forcing users to re-accept it (and either locking them out the forum or simply barring them from posting until they accept it)

Ability to edit email templates from the admin panel

Ability to 'soft ban' a user, similar to Annoy User

Mass move topics is now more selective than just 'everything in a board', you can pick boards to move from, as well as other criteria
Merge two user accounts together
Moderation centre shown on the board index as if it were a real category (but it isn't a real category, it just looks like one)
Centralised popup system even for general prompts and OK/cancel notifications, which is styleable (unlike standard browser ones)
Custom fields now have proper privacy controls, are drag 'n' drop to rearrange the order and can optionally be shown on the memberlist too
Pinned topics can be drag 'n' drop rearranged
Group access can not only be given to boards, it can also be revoked (unlike SMF)
Board access is also split between seeing it and entering it, including the option to add a custom message to users who can see a board but not access its content
The SMF 'member options' area is replaced with one that doesn't have 'per theme' hassle and is actually quicker to use to set what you want
Proper timezone support for users (set timezone on registration, not a number of hours offset... even daylight savings works perfectly)
News items are also drag 'n' drop for reordering, show the bbc editor interface and also have privacy options attached now
Better internationalisation support in general
Logins can be username/email, username only, email only
Customised selectbox that shows images and other HTML (useful for selecting icons)
Search removed from the main menu and made in to a sexy popup
Use of HTML5 inputs wherever possible
phpinfo() shown in the admin panel
Your buddies/contact list is shown in the PM area with a nice clicky interface
Admins can now set which boards can be ignored by users
When splitting a topic, the new topic can be in a different board
When issuing a redirection, you can also set the redirection topic to actually redirect you automatically (and if it's to a board you can't see, a nicer error is shown to you)
Topic privacy
Topics have a good meta description now
This doesn't include the various and numerous, SMF bug fixes or the various underlying changes required to make any of it work.

There are probably other things I've forgotten, too. But of course, it's just SMF with a few new features, right? RIGHT?!?! And it's not like we're adding new features or anything.
Of course it's not. I don't know why I'm letting myself get annoyed. I find it amusing that the person who makes such comments 1) does so in a place where he KNOWS I won't normally see them and can't defend myself or Wedge (someone considerately informed me via PM), 2) came here only a few days ago to ask for my help with his project, after all the shite I had with him a bit back and seemed *surprised* that I wasn't interested in helping them and 3) tells me off for things before doing them himself
Mind you, said person is talking about his own forum software in Python and Django which will obviously be better than anything else out there. Assuming he ever finishes any of it. This is after both his own PHP based software, and his subsequent SMF fork, have already fallen by the wayside.
