I realised this week, when trying to upload some more speaking resources to our LInked Up Project wiki that we had run out of space! Not being completely up to the minute on all the alternatives to Google groups, and finding that 100MB was definitely all I could get from one Google group, I opted to make 4 separate French, German, Spanish and non-language specific groups. Links to the 3 language groups are in the sidebar to help people find the material easily. The original group is going to be the non-language specific one, although currently it is full of all the resources from the first part of the project. Having felt most chuffed at the ease with which I'd created the new groups, I'm now finding that there are some uploading glitches (well-documented in the Google groups forum unfortunately!) so I'm letting it have a rest and I'll go back to transferring the rest of the material later!
Hope this eventually proves useful!
