side note:
Some of the original vBulletin developers have moved on from that forum software and are working on a new board/forum software for websites, under the name the XenForo Ltd.
It looks to be both user-friendly and modern, and be worth considering with the site redesign and updates:
https://xenforo.com/.
And if you need forum consulting, Jacob Bunce (jakeman) is one of those developers, and though he is assisting XenForo as a side-job to his profession, he is incredibly helpful and provides a lot of information, if needed, as an interest/hobby/background expertise.
Also, I can provide any assistance as I've deployed several websites, UX/UI and graphic designs for the my current employer, the California State Legislature. (I'm looking for a career and job shift anyway, and would like to contribute any way I can)
