It's also so that the more it's used now, the more sense all feature will make. Currently a lot of old content appears on places, but once more recent threads are updated/created, thing should become more sensible.
Obviously things are different from Vbulletin and there are also for us (staff) some annoyances, as it's much harder to assist users in getting their password and/or email changed.
But Discourse is fast,secure, feature rich, mobile-friendly, allows logins from social networks and utilizes all modern web technology of today so somewhere it has to be an upgrade of good old Vbulletin
That said, I fully understand that it's harder to get used to than if we switch to software that wasn't so drastically different.
More importantly, if you have annoyances, it would be even better to post them. Some might be due to settings we haven't discovered and that can be changed! Or else we can change something on the layout, we're very open to that.
When it makes sense and is technically doable, we will certainly try to accommodate any wishes!
