I am looking to create a custom post fields addon for my forums.
The addon could be based on https://xenforo.com/community/resources/th-custom-fields.885/ but doesn't need to be.
Depending on which forum the thread starts then the user will have the ability to fill out additional fields.
Additional fields will only be available for the post that starts the thread.
Additional fields will be placed within the post like it has been done with the aforementioned addon.
I have PSD files, full description with examples from another site (based on VB though) and can provide a development environment.
Note that I am planning to use [BD] API to connect XF with WP, take this into account.
Please contact me for details.
