If you look at Paul M's VB4 importer, it brings in all blogs, cms, groups and forum data... the script needs to create the necessary redirection for any of the four URL types used in VB4 to the imported data via that already public script.
I request the script is public and supported... obviously tested via users here first in beta and ensure faults found and rectified, etc... then I will gladly donate the above money to the developer of the script.
<Added> This is time limited as I need this before 20 Nov 2010. If anyone is taking this on, then please let us know here so I know its in progress. After 20 Nov 2010 I retract the donation for this addon. If I know its in progress, then I am happy to extend the offer and wait if it can be released in Nov.
