the forum is FULL of old posts/threads that give MASSES of valuable information on this, i'd suggest you use the search feature to tap into it.
a lot has changed in the last 3 years ( and ALL years) so reading past threads is how i learnt many things and its saved me MANY $$$$$
i also found when i posted and asked a question that had some knowledge behind it eg: a thread example, i got a better reply.
just look at some of my early posts and you will see i copped a BEATING from the pros
....... still do !
except for current events i do not think there is a question unanswered on dnt already, its the WIKI you want.
