I've seen it in other platforms like vBulletin or MyBB (with Xthreads mod) and I would really love to see it in phpBB3. From what I need, this is the only
thing that I miss.
It doesn't have to be like a big/complicated system, a simple one would do for everybody I believe. For example it can be an extension that it can modify a certain forum
or create a whole new page
for the system. A list of what this extension might have as features could be:
Product Category (e.g. Birthday Gifts, Furniture etc. that the user can specify into his/her liking)
Website of the product/manufacturer
This is just a first thought of what an extension like this might have as a basis. It could be nice though to give the user the freedom to add additional fields in some way. I'm not very familiar with extensions/mods development so please, don't get me wrong if what I ask is too much
I also would love to hear some thoughts on this by developers and non-developers.
