I've tried poking around for this, but as you may appreciate searching for the term "trouble ticket" yields a whole lot of nonsense.
Bascially I'd like to use wordpress to allow registered users to post trouble tickets via a form embedded in a wordpress page.
The faux trouble tickets would just be regular posts to a category as defined in the form, and attributed to the account of the person posting the ticket, even though that person doesn't have author level privilege.
Security and authentication etc isn't a problem as this could easily be handled via template conditionals and .htaccess -- not that this is even required in my case, as the site is for internal use only.
Once posted, of course... the "ticket" could be commented on just like any other post, and of course "closed" by blog admins who could turn off comments... so this functionality isn't required, that's just up to us to theme it correctly.
If you can point me to something like this as a wordpress plugin I'd love you long time, but I'm not holding my breath, so I have a couple of offers to any plugin authors reading...
If you see value in this project and would like to add it to your collection I would gladly chip in with a financial motivator.
On the other hand, if you're not interested in making this plugin part of your contribution, then I'd certainly be interested in commissioning the work, and making the plugin available myself. Obviously this would cost me more, so I'm hoping you'll want the credit.
All contributions welcome.
Thanks for your consideration.
