The second of the original mock-ups was too small for me to see it
clearly,
Yeah, I don't know what happened to the original. At the time, that was deliberately half-size because I didn't want to get into the minutiae of the actual text.
And the current version is really an easy-to-debug proto-template; it's very functional, but it also sprawls all over the screen. And it's seriously broken, I noticed when I was working on the mockup; there are unclosed DIVs and other evilness (at one point it validated, but I've dinked with it too much since then).
At this point, I'll probably go with something like the (recently-added) "semi-emulation" mockup, just because it gives us more real estate. Graphics and colors are, of course, just a matter of theme, and the Phoenyx' will be somewhat different... likely still white/black/red (ugh), but less of the shiny-red.
What I *really* want is the server logs off an actively-used phpBB and/or vBulletin installation, just so I can analyze them for the typical usage patterns.
If we had a server running PHP, I'd actually consider starting a phpBB site just to get that information...
