Sorry for my English. Is it an idea to make a personal catalog in Bricklink in
which you can inventory the sets which you own? And maybe inventory missing parts
or sets and put them on your wanted list or order them?
I looked through the open catalog requests and there doesn't seem to be one
for this. It could be a site development issue, but I'm not sure so I'm
making it a catalog request.
There are 3,000 books in the catalog and volunteers willing to do a little work
to make those entries more complete. It won't be so easy if we wait to add
the alternate item number field until we have two or three times that many books
(or more) in the catalog.
