Especially when you realise that some of the things fixed in RC4 were actually fixed prior to RC3 but chosen to not be released for 'reasons' that I never quite understood.

As I understood it there wasn't supposed to be an RC4 but apparently the scale of changes in RC3 made them think otherwise.

From outside (I requested account deletion months ago) it could look like no-one has a vision for what SMF should be and this is just about rearranging the deck chairs until someone has a vision.

2.0 debuted June 2011, 2.1 started soon after to be a small interim release while 3.0 was planned out.

When i rejoined the team in 2013 I was assured 2.1 was “almost ready to go” with just a few bugs, but what I found was a piece of software that, while yes, a technical improvement, I didn’t understand why anyone would upgrade to it.

So I put in a couple of big name features, lead something of a slight UI overhaul (for which I’m still being criticised for ever though all the other platforms long since did much the same) and left again in early 2014 after having a long and stupid debate about something trivial - and I realised there wasn’t a lot of point because in an environment where “everyone has a say”, you guarantee making “the least worst decision”, aka death by committee rather than just making a decision and having a point of view that people can get behind (or not).

I found SMF easy enough to install and use. The Admin panel was OK and had some good information. I didn't like the way it was laid out in sections and subsections though. It was hard to find out where to make changes to users and boards without messing up some other interaction.

I kept hoping for a simple menu tree type layout.

No, I can't cite any specific example right now as it's been too long since I tried it. And I've slept since then.
