Would you like to make some money? And make EN World even cooler than it already is?
Well, I like money, and I like ENWorld and I am actually looking for a new job...
A big barrier for me is that my current day job ties up enough of my time that it's hard to commit to a second project and maintain a family life, so I'd be hesitant to volunteer to, so as to not let anybody down.
Though I'd be happy to help out where I can or review some designs.
Here's some techno mumbo jumbo on me, and what I've found in doing this kind of work. Might give a sense of perspective when considering candidates.
I've worked on VB.NET and C# with SQL Server to do web applications and linux with PHP and MySQL for web applications (including having to completely rewrite from one platform to another due to politics). I haven't done anything with vBulletin or external apps (all my work was for internal corporate use, sadly no public portfolio). I do have a a patent on one of the things I made.
In general, I can design the rough DB in about an hour or two, fine tuning it as discussions with the customer reveal more complexity.
It should take less than a day to code up the objects and GUI needed to administrate a table in the DB. That's 1-2 objects per table with admin screens (UI) to make it work. Some are faster than that. The point then is, a basic app* can be worked up from nothing in about 3 months or less, and then fine tuned to make it look pretty and the customer facing screens to be made more robust and user-friendly.
*by basic app, I mean one with 20-50 tables. Smaller stuff, goes faster, especially when you've got existing screens, libraries and frameworks you can use.
I'm a little busy this weekend, but if I have time I'll post some table definitions that would model a User having gaming preferences, that queries could be written to "find who likes what I like and is nearby". It's probably 3-5 tables to do it.
With that, you could compare what others propose, and identify some shortcomings (and skill set differences). Nothing's more dangerous than an incomplete design that makes expanding harder.
