I would recommend bringing back the Category for PHOTRIO donation items. AFAIK there used to be such.
IDK if there ever was, but it's indicated at the top of an ad if a donation is made (or intended):
The way I see it, it doesn't make much sense to make this a category like 'For Sale', 'Want to Buy' etc.
I can imagine some benefit in making the 'donation' tag appear in the list of ads, but I don't know how complex that would be from a technical viewpoint.
Keep in mind that when it comes to imagining new boxes to tick, we also need to balance between usability and completeness. We could append a massive survey along with each ad and/or have enormously long lists of options, but all it would cause is no-response. The present system with tags is already problematic because as it is now, it requires active maintenance by posters to change/remove a tag once an item is sold or withdrawn.
At the risk of senseless proliferation, is it worth considering a category for closed/withdrawn items to be used for items that didn't sell, or those about which the seller had second thoughts?
Yes, and in fact to the best of my knowledge we had agreed on this among the team of moderators, but
@Sean hasn't gotten round to implementing it yet. He's been really busy last year. The present workaround we now sometimes use is to simply remove the tag altogether in such cases.
