Kudos and a question about Last Activity date after import
 

I'm new to vBulletin and have just finished importing an old Yabb 1.4 board to 3.8.2 and then upgrading to 3.8.3.

First, I want to say thanks to all involved in producing vBulletin and ImpEx as the setup, import, and upgrade all went darn well considering the age of the old board and my inexperience with the software. Thanks!

Now a question.

After the import, probably because Yabb doesn't record the date of the last post for each user in the .dat file, the date of last activity for all our members is now what I assume to be a default 12-31-1969.

Is there an easy way to get vB to read the date of the last post for each member, all of which were recorded during the import, and use those as the date of last activity in the database? Or something else that will accomplish the same thing?

Thanks in advance for any help or insights.
