OK, some updates:
I've altered the font sizes for the forum texts so they are the same as the "TBF Classic" style.
An issue with Quick Reply and Firefox browsers has been fixed.
The "currently reading" info is now back.
The left menu "brown bar" font and colour has been changed so it should be easier to read - let me know if not. The idea of this menu bar is that it will expand with links to other areas of the site (reviews library, links directory etc) which have already existed but weren't as well known about.
And lastly, if you really can't stand the new look, you can switch to the old "TBF Classic Style" - you should see a drop down menu near the bottom of the forum pages. This will only work on the forums and not on other parts of the site.
