I am not connected with the CardTarget ownership but I have been actively corresponding with the current custodians-
this started when I offered to add the M116 set to the site, which I thought was a major gap, and I finished that about a month ago. There are stubborn kinks with some of the variations in the set that we are still working out, but the basics are there. I have moved on to classifying T207s, which will take a little while, but it is in process.
I also got the T205 and T201/202 sales up to date. There are a great many T206 auctions waiting to be processed... anybody want to take those on?
My sense is the proprietors are definitely interested in adding new stuff and keeping the site active; the main issue is time. If you want to help, consider volunteering to add a set you're interested in. It is a free service, after all, which is why we like it - and I find the process rather enjoyable (plus you learn a lot more about the set's values).
