Went on a presentation course a few weeks back where we had to be armed with a 10 min presentation of our choosing... I went for my fav sub ject and managed to space it for 14 mins and another 5-7 mins of questions... the longest of them all
You can download and view it at....
You may need MS Powerpoint viewer... this can be found here...
I'm in the process of updating my web site too which will have far more detail around it than this so watch out for that
PS The presentation was mod checked before posting
