I don't think that it is very strange that the old site is hardly being used anymore. Untill today i even did not know that it was still possible to use the old site. therefor i tried to find the link to the old site.
Searching on the new site and searching on google did not give any results. I tried for half an hour to find the classic site. At last i saw a forum posting that the link was http://classic.gps-speedsurfing.com/
If i had a choice i would keep on using the old site because the old site still offers the possibility to post manually and better supports other than doppler devices.
