Why isn't ED using free software on the forum? Why does he wear trainers? Why does he have long hair? Same answer to all of these things; because he wants to. I only say this as sometimes there seems to be this feeling of having to justify either spending money or using software which isn't open source, or whatever else, which simply isn't the case, ED is free to do whatever he likes. From my perspective which ever gives ED the easiest life is the best option! Let him concentrate on other things rather that forum software.
