After a great amount of thought , I have to do whats best for my community, I was one of the very first customers on xenforo. The time has come. It is partly my fault for relying on 3rd parties to bring the functionality we needed , so now we are trapped on old software awaiting 3rd parties to update. I am not willing to wait when the functionality already exists and is professionally supported by 1st party elsewhere especially when i already own 2 IPS sites. Pros of switching to IPS from xf Groups functionality will be greatly improved and the vitality and use will increase DEMO - https://www.progungroup.com/index.php?/clubs/ Groups by location - Members will be able to find groups closest to them ACTION ITEM: Will pay for custom development for software to notify you when a new member joins within specified radius set in your admin cp. Links Directory functionality will be greatly improved DEMO - https://www.progungroup.com/index.php?/links/ Our links directory is a disaster Site updating would decrease from hours to minutes Increased security and spam control Brighter more Innovative Future 1st Party support for the features we need most Standardization of softwares for staff Plan for monetization Professional widget control Improved Nav Bar Ease of use such as posting and uploading photos Forum Index much cleaner and more functional Registration and log in more obvious Better Permission system Reputation > Trophies Cons of switching to IPS from xf Styling more difficult Customization more difficult Upstart cost Renewal cost SEO will take a hit Loss Investment from xf core and multiple addons Loss of relationships with xf family and addon developers, some people i wont miss some i will Direct line of communication to core developers will cease Post Bit/ Message User info Customization will be lost Advanced profile fields more difficult So i assume everyone is going to jump all over these items and break them all down , let me say that some are opinions, and I'm entitled to my opinion same as you.
