I've gotten a few of those myself.....
Update:
I tried again to join the team and the link was there today! So I joined.....
will be helping out if it gives me any work..... Last time I was connected it wouldn't give me any....
Update II:
I've joined on Haf1, I don't have the executables and it doesn't seem to download them.... just sitting on an empty directory, so it really wouldn't know what to do with them if it got some....
