The forum looks very simple and nice.
I just check the site to see if your telling the truth and your right , thier site loads fast and its simple . btw im only using a mobile .
The only problem is that getting users to a new forum is one of the most difficult task anyone can undertake.
Its hard but its possible to fill out the forum as long as you have enough budget for doing giveaway or promotion to greatly attract people .
Anyway the op posted it last year so i expect that they are now many sign ups on thier site . i see that the site mainly focuses on sports . its a good way to lurk and gather inside infos on them if your onto sports
