Thanks for the suggestion rick and for the explaination dinos. I hope this is good for now. At the start I wanted to include as many people as possible to get people interested and get the thread going. It may need some revision and housekeeping now. I will try to check here more as I don't seem to get the email notification everytime there is a post. Excellent time k|ngp|n. dinos, it looks like we need to get busy again. Post has been updated.
