Any chance of looking at the stats progress please. I am not sure if stats are exported or not but the table as listed in Top Participants seems to be way out and old. There are a total of 1594 members registered and only 186 showing a score. That means 1408 have not scored since joined? Most projects adjusts these totals instantly as it changes and some adjust it every hour. It would be nice to see who is doing what.

Hi Pete. Thanks for your observation.
Stats are being exported in the usual way, and as far as I know, the info in the top participants list should be updated accordingly.
The server database ran out of space this weekend and probably some stats information was not recorded, but most probably his is because we have WU available only from time to time in relatively small sets, so they tend to be computed quite fast. There is a good chance that people join but with no WU available.
Nevertheless, I'll check this in the next days to be sure that everything is running ok.
Regards,
Javier.
