The "Best answered" add-on is absolutely recommented for any forums that requires an question to be answered. The appearance of the add-on is very sleek.
The support of the content creator, AndyB, is absolutely amazing. I had some issues with the add-on due to not being compatible with other add-ons. Thanks to AndyB the problem was fixed in no time. In a few hours of mentioning the problem he updated the add-on.
The price for this add-on alone is reasonable. However, you do get a ton of great add-ons (all add-ons) created by AndyB for free which makes it absolutely the best bang-for-buck add-on.
For price, functionality of add-on and support I would recommend this add-on (along with all the free add-ons included) to anyone.
