greetings - thought i'd introduce you to the search function of this wonderful site. this topic has been addressed many many times by all sorts of folks. rather than scrolling though each message to find posts, use the search button that lives above the index. that should get you started on much of the big picture stuff without having others repeat themselves. of course, if your specific questions remain unanswered, ask away. also feel free to post the info that you have compiled, possibly saving someone else the same process in the future. cheers, and good luck.
