Regarding vBulletin:
I agree the navbar is BLOATED.
The search dropdown is a huge MISTAKE.

Regarding your modifications:
Your target audience understands the function of "breadcrumbs".

The "You are here" prepended to the breadcrumbs will only confuse people. If you really want to add such a feature I recommend that you append "You are here" to breadcrumb; also, you may want to style it different from the breadcrumbs. On your site, the "You are here" looks like it is part of the breadcrumb. eg. Am I at "You are here" or "WDF v5 sneak peek, part 5"?

I would actually leave "You are here" out of the "breadcrumbs". Now-a-days, breadcrumbs are standard and visiible on all big sites. In other words, people understand what "breadcrumbs" are or could easily intepret the function of the "breadcrumbs". (repeat)

The 23k CSS file is a bit bloated don't you think? I do understand that it is needed especially for something like a vbulletin-run site. But, you may want to split it and use what is necessary. In this manner, the initial load for a dial-up user will not be as bad. (First impression is important.)

Overall, I think the project looks great and applaud your effort. :up:
