There was a similar discussion some years back when PlaymoDB was also falling behind on set updates etc but Heather politely declined any help offered. In Klickypedia, everyone can contribute and update sets, and so far it is working nicely. If more people could help in data entry in PlaymoDB I believe the site could have been easier to maintain.
One of the most valuable usage of PlaymoDB (at least for me) was/is to find out which (spare) parts of older sets can be found in the sets that are on sale, or can be available in the market. As time passes by and latest sets found in PlaymoDB become obsolete, then this search feature losses its value and to an extend so does PlaymoDB (which is sad).
