I offer a server with 2mbit synchroneous connection for OLFSL. It's currently set up for 23 connections, though never tested it with more than 10 I believe that 2Mbits should handle 20 racers normally. It has been mostly private server so far but there's not much racing going on lately, so I would be glad if it could find some use. Only bad thing with this server is that it may lag a bit on normal workdays (monday-friday) between 5 AM and 4 PM GMT (8-19 in Finland) because some people occasionally use that machine for work. But as far as I know the OLFSL races usually take place at different time.
I'll probably join OLFSL too if there's new season being organized and I've got ELS ESCC league finished by that time.
