As a newcomer to the forum world (I spent the last 7 years managing high-traffic Wordpress blogs, but I never messed around with forums until now), I've spent the past few weeks reading through the XenForo forums trying to take in as much information as possible.
While I see numerous people say that XenForo can run on a shared host without issue initially, I'm curious about when we'd need to make the move to a VPS. Is there a point where one hits a certain number of users/users online/threads where shared hosting no longer proves reliable, at which point a VPS is needed?
I'd much rather do things right from the get-go rather than deal with a messy migration in a few months if we're going to outgrow things in a hurry. (Unless the host offers automatic migration from shared to VPS, in which case I'm fine with going that route)
But given that this is all new to us, I don't want to throw away money if we're going to be fine on a shared host for a year's time or something like that.
