I started with XenForo almost 5 months ago and I think the version at that was 1.1.15. Anyway since that time I keep adding so many Add-ons. Most of them were very necessary to my community and some the community's members were pushing me to add them. I am not an expert person and therefore I lost a lot of time by reading and insulating these add-ons.
My suggestion to you guys
Why do not you have an agreement with these great programmers who are contributing to xenForo.
I know it's very difficult but at least the most common add-on to be pre-installed (default) in one of the coming versions and call it the golden version and make it an optional copy for at least $ 200.
