How to get old forum layout?

I think you mean: Do you like the new forum?

@pathogenex,
While I agree there are certainly things that could be imprioved in the new version it is, in my opinion, a big improvement once you get used to it. One thing you don't see is that behind the scenes if there is a problem* with it then the problem gets reported to Discourse (who provide the forum software) and they fix it. The old forum software was unsupported and getting problems fixed was, well, a problem.

Discourse is way more stable and gives minimal, err, problems (do I keep typing the word 'problem'?)

So, no, it's not perfect, it's not the way everyone wants it but it is a big improvement.

*By problem I mean if something goes wrong with it, it gets fixed.
