Kris, Over the past year since I bought an S5, and since the TDI subject has been pretty intense, I have read and posted more on Audworld than I have in a long time. Back when the forum changed formats (in 2009?) and many ( especially the Mk1 TT crowd) migrated to a new forum that used the old KAWF format, I moved too. The owners and knowledge base for the TT was there and that format with its " track thread" feature allowed a more conversational feel.
I had a Cayman for a while and read and participated in those forums but never found that it was easy to follow a conversation thread in the way one could with the old KAWF format. Refreshingly though in the past year I have found AudiWorlds format to have features that make this very easy. The best feature is the ability to click on " My recent posts" under ones name at the top and see if there are new replies to any thread in which you have participated. THIS makes a huge difference compared to looking for subscribed threads as you have to do in other forums. I don't know why others don't offer this option but I am glad it is here! Good job guys.
