Does anyone use the Club Class?

Does any country run competitions in the IGC Club Class?

USA does not. We have the Sports Class, which allows any glider to
enter, and another Sports Class (called, locally, the Club Class)
which uses a restricted list of gliders that is different from the IGC
Club Class list.

In another thread, in response to a question about inclusion of the
PW-5, Andreas said:

"Sure - the only limit to CLub Class in Germany at the moment is the
upper limit of 106 for the index."

which makes me think that Germany doesn't run any IGC Club Class
competitions.

And then Martin reacted to Andreas by saying "Its the same in the
UK...", which gives me the same impression about the UK.

Three major gliding countries that don't use the IGC Club Class. It
makes me wonder if anybody does.
