Not websites, but two resources I found invaluable when dusting the rust off (both available in ebook format):
1- "Practical Recording Techniques" by Bartlett and Bartlett (new edition is available, haven't seen the new one).
2- "Mixing Secrets" by Mike Senior.
Both pretty in-depth for a beginner, but easy reads. Great "refresher" material if you've been out of this for a while. I've gone back to both a few times since reading through them the 1st time. If nothing else, they can help fill in the down time between projects (I'm not a videogamer, so prefer to read).
