Well this website sure has the modern feeling, even though isn't everyting really big? But that's okay it's just habbit from the old version i guess.
I need to be honest that there are a few things i miss / don't like here.
There's no link to the wiki in the top menu. I liked more when the reponse window have been part of the thread itself as mostly i've been reacting to something so i could write and see the previous posts in the same time.
I miss the wall and the who's online box as it might have not been the most used thing, it makes me feel less connected to the community now. Why did you remove the Lua category and option to filter by categories? Whats the point of having them if you can't filter them.
Maybe you could forget about the pinboard and just add a left side panel to the main page of the forum with the online box and categories.
Last minor thing, the search bar could be visible even above the posts itself.
As Nigec, i don't want to offend onyone, i respect you are trying to evolve this web.
