Joe encouraged new hack requests so here's a few.. I'll find the links and more relevant information later as I'm in a hurry.

combine the post awards hack and the user award hacks and improve the functionality/add new features to both.

combine the 2 different event attendance hacks.

a fully functioning and customizeable shopping cart hacks.. allows you to accept paypal and other web payments + credit cards directly on your site. support with https.

a ladder/tournament management hack, sort of like mygamingladder.com, but with more features.

I like the idea of combining similar hacks, especially if the developers are willing to work together on those projects.

You beat me to saying team work :p. The shopping cart sounds like a great team project As for the award hacks I was already making one like that. Though if you could pm me to exactly how you want it so I can check it's what you want and I'm not going in the wrong direction that would be great.

yeah, I'll be more specific tomorrow. I work 4pm to 4am on the weekends so I was just getting something in before I forgot.

post award hack: Post Award Hack - vBulletin.org Forum
suggestions:"maybe some nice features to add/consider would be ability to define award categories, upload post award images, maybe a forum which all awarded posts get copied to or a page that just list them all (besides the search function). if you add more award categories maybe a page like that could be sorted to show awards by their category.

also maybe an option to award a thread. this could add an award thread icon to the thread list/view page which would also be a nice distinction."


yet another awards system: Yet Another Awards System 3.5 v2.1.2 - vBulletin.org Forum
suggestions: "if for future versions you could make it so you could also choose to award a usergroup a medal so that each member in that group could receive it instead of having to do it one by one? or maybe even the ability to award a medal to a usergroup instead of a user."

suggestions:Intergration with the event attendance plugin.
Customisation of the order of the custom fields in the thread title.
An option to "import" all the previous events from a Calendar into threads.
Extra post options support (Attachments, Post Icons, Sticky etc).
Custom ordering of the %datetime variable.
Custom ordering of %custom variable.
Better handling of recurring events."

event attendance: Event Attendance 2.0 - vBulletin.org Forum

rsvp hack: Farcaster's Event Attendance - vBulletin.org Forum

how about a hack to add custom admin permissions to custom admincp entries? so, for example, if someone has vbacmps installed this hack will detect that it created a new menu option in the admincp and let you choose whether to include it in the admin permissions when you decide what a person can/can't access.
