I think the level of maturity and knowledge on this site are very great.  The previous V.1 of this site was very user friendly and I was in and out quickly.  V.2 takes a great deal of time to load pages and is slower to navigate.  Hence I usually visit Rennteam and Rennlist.  I believe the quality, and gentlemanly behavior make me keep coming back, plus their is real genuine insight on this forum.
