Hi Jim Thanks for deleting the extra posts. Don't know quite how that happened (but sometimes my netbook does funny things).
In answering Helchis question earlier I was drawing from my own knowledge in the area. Thought by doing this it might take some of the pressure off the official moderators, since I am aware that there is shortage at the moment.
Have found over the last wee while that I do sometimes know stuff that others aren't fully aware of. Hence sometimes I try to help a wee bit if I feel I can.
