I'm not too concerned with the problems, as I got it working on my site just fine I'm just not happy with the way it works now. You have to approve almost every modification people want to add, unlike the old setup (Version for Phpbb2)
So if you want to add a new JLT intake to your 2003 Cobra, you have to have "JLT" approved before it can be added and then you'll have to select "JLT" from the drop down menu. They have too many "drop down menu" choices. It should be
Category - Drop down menu to choose from the available categories
Manufacturer - Text box to enter who makes it (does not need approval)
Product - Text box to enter what the product is (does not need approval)
Purchased from - Drop down menu from available vendors, can be skipped
Price - text box to enter price
Installed by - should not be a requirement, most people who modify cars usually do the work themselves...
It just so much work from both the administration and the end user to have a new modification added, that no one uses the garage anymore.
