If your favourite Telecoms subject isn't mentioned in the list, then let us know ! The THG can't do it all alone, it simply doesn't have the resources but, collectively it can achieve a great deal. Please make an effort to share your wealth of knowledge so that everyone can benefit. And remember, although it might only be a hobby, let's do it professionally and have some fun in the process!
