Heyya & afternoon there Jim:
There is a good deal of frivilus information in this thing. However, there is a welth of good information as well. No doubt for those of us who are totals. Using the PSREdit is still the easiest method of dealing with the 500.
I'm posting the link. However, it currently isn't working for one reason or another. I'm guessing the site is having issues. It worked a day or 2 ago. So, I'm relatively certain it hasn't been taken down or anything like that. I'll check it back in an hour or so.
