Some 'noob orientated' help for R4 is required!

I am extremely impressed with R4, and should like to use it in a (charitable, non-profit, no-entrance fee) disco this coming saturday. I have already spent many hours reading posts in these forums in the hope that I can learn how best to use R4, but I am afraid that a lot of what is said in 'computer speak' goes over my head. I consider myself a proficient computer user but have not got into scripting and coding. Please could it be explained to me, in layman's terms, how to launch video clips to play in R4 using the web interface, how to download and add more vidcap scenes, and how to announce images using the web interface. If I recieve enough information I would be more than happy to write 'A noob's guide to R4' and post it on the messageboards; this could surely only boost the distribution and sale of this excellent software!
