He hasn't been around for a while, my guess its something to do with the school holidays and taking a break with family. When he is around he always appears on the forums every day or so, Im sure he will contact you very quickly when he is back.
No way you could try out your mini with the sail you have? Probably wont perform 100% but it could be fun for a few days

Im sure you could rig something up just to get it going.
