I have joined that site too but it seems that platform is full of spammer who post spam content. I think Bitcointalk or Altercointalk is much better than that platform. I also did not like their website layout.
So far, nothing can beat the original forum -- BitcoinTalk -- much like Bitcoin not perfect but still the most dominating cryptocurrency. All other forums in the cryptocurrency sphere are having a hard time managing spams and getting the audience that they are looking for. I am a member of other forums as well but my main activity is here.
