Ability to add fully manual entries in the "Collection" section as a workaround for titles that are missing from the site

If one has Contributor Privileges they can submit missing game titles. However somebody who does not have these privileges (most Users here I believe) cannot keep a full and thorough database of their personal collection on this site, as a lot of games/items are not listed.

Unfortunately, even with the immense number of games here at pricecharting, I regularly bump into titles that are missing either fully or for one or more regions.

If we could simply have the option to add any manual entries for ourselves as well as any details for these entries (value, cost, condition etc) we would be able to put together a complete record of our FULL collection.

This would also be immensely helpful in keeping track of other types of items that similarly do not have any record on the site, such as:

- Promo versions of games
- Promotional items (standees, posters etc)
- Kiosks

- Press Kits
- Arcade machines
- Any non-video game items that usually people still consider as part of their video game collection (video game board games, figurines, plushies, books etc)

....pretty much any others video game related items/memorabilia (from free stickers to contest prizes)

These would naturally not be linked to any pricecharting metric/value/entry as they are not available on the site. We could either skip adding the value or value them based on our own judgment or our own ebay research.
This would of course NOT be public either, anybody could add any entry they'd like for themselves under their own account.

I believe this would be an extremely useful feature, because being able to upload 70-80-90 % of your collection but not everything, ultimately defeats the main purpose of the "Collection" section.
