Sometime in the next week we will migrate the forum to Xenforo. You will notice a default "This forum is undergoing maintenance" message. Probably take me about 1-2 hours to convert the site. vB4 is end of life, it's not security supported software anymore and there are active exploits for this vB4 version. vBulletin is now on version 5 and no one uses it. vB4 was not even adopted by many. vBulletin 3 was the gold standard, then all the developers left after that to start Xenforo and now it's the gold standard. It's super secure, extremely easy to use, fast and robust. The UI is a lot like a modern vBulletin 3. It has the ability to copy/paste images into Quick Reply like Gmail, the search is awesome, the design is responsive so it works great on mobile devices, it's really secure software. https://www.cointalk.com/forums/ https://www.homesteadingtoday.com/ Those are two big, big sites running it. That's a more default version of the style. More like vBulletin. I will make the design very, very close to this one so the change over is not too drastic.
