We have now opened a commercial services section here on the forum for registered users. If you have a Fabrik project that you wish to have someone work on for you, post it under Help Wanted. If you are an application developer and wish to earn some money helping others, post your details under Fabrik Application Developers.
Both of these are unmoderated. It will be up to both parties to work out the details and come to an agreement.

I am of the opinion that styling is part of templating, and as such should be handled within either Joomla's or Fabrik's templates. This allows for a single "source of truth" when it comes to styling a form, - the template's css file. It also allows you to use things like firebug to modify the css and copy and paste the files contents right back into your template's css file.Imagine the simple but huge power of a simple CSS parameter in list, form, group and element.
