I encourage others to share the systems they find. If you post it as above then its easy to run a future test in a week, month, year when there is more data in the database and compare the results. You can then see if the system held up over time. [QUOTE]

G'Day UB, I agree it would be great to share ideas to this extent, but the problem is there are some charlatans, i.e the dregs of society who also peruse these pages for any idea that MAY hold water, then package them with glitter advertise it in THEIR so called magazines, and sell the blue dy things to the mugs, sorry to use the word but mugs it is!

It has happened more than a few times.
