Not only would most people agree, so would the guy who created the Modern SRD in question. Me.
I hope I was sufficiently clear that my SRD is a complete rip-off of S&S's.
The online Modern SRD is, as far as I know, accurate, but it does not include any of the Urban Arcana information. I haven't gotten around to including that because it's a lot of work and I'm lazy.
So far THREE people have volunteered to do it for me. It remains undone.
And the key thing missing from ALL the SRD's is the experience point tables, and the method of character generation (it never says "roll 3d6 for each stat").
But I'm glad people like it. Always happy to have feedback!
