So che questo è stato discusso in precedenza, ma volevo verificare se sarebbe stato implementato.
Abbiamo la necessità di avere una categoria nei messaggi privati per determinare se i messaggi privati sono contrassegnati come risolti, ecc., all’interno di una categoria specifica.
I think PM tagging is coming to Discourse:
That could work or you could set up groups since they act as categories(inboxes) for PMs. Then you could have PMs move from inbox to inbox.
I think the tagging or even some type of Solved/unsolved extension of the plugin for PMs would serve you well.
I was excited to notice yesterday that if you edit a PM’s OP, you can now add tags. There doesn’t seem to be any other UI yet but work on tagging of PMs seems to be underway. 
I didn’t think about tags in that sense. That could very well work for what we are doing.
My primary concern is I need to ensure that however I implement can be combined with the
solved plugin.
This could be quite interesting.
Yes @tobiaseigen, it may available sooner PR #5610 
But the UI you mentioned is a bug. Anyway it will be fixed by the above PR itself.
yes - between group inboxes, tags, assigned and solved we could be getting towards quite an excellent ticket system, with no balls being dropped ever again. 
wait, what? why am I always discovering bugs and hoping they are features… 
super excited to see this underway in any event.
PM tags feature is now available in core. Enable the site setting allow staff to tag pms to try it.
Hi There. I see this discussion from '18 on adding tags to private messages. In my case, I want my users to be able to send private messages to themselves and to other users, and to be able to organize those messages for later viewing.
Is it possible to have users select a category for private messages?
Is it possible for users to add tags to their private messages?
No, it is not.
No, it is not.
Ok. I’ll try posting to market place to see if adding cats to private messages can be coded in.
It’s a database constraint so quite close to the metal and risky to change as plugins go and may have some unexpected effects. It would require core to add support imho.
Hmm. Thank you for that info. I’m anticipating the private messaging will be an important part of the forum, so users may be creating a lot of them–they’re likely to use the private messages as a way to keep notes. I’m just looking for an easy way for users to look back over their private messages in an organized way.
I’d assume that grouping the messages into categories is the most obvious way to do it, otherwise tagging. Could there be another approach?
You could use custom topic fields. That would be safer.
We could certainly look at it if you post in marketplace.
I’m not familiar with custom topic fields, but sounds like that could be a possibility. I’ll post to marketplace.
Le categorie per i PM non esistono ancora, anche se i “tag per i PM”, introdotti per lo staff, sono ora disponibili come impostazione di gruppo (pm tags allowed for groups), quindi è possibile aggiungere un livello di fiducia a questo, o un gruppo personalizzato più specifico, e loro saranno in grado di organizzare i propri PM con i tag. 
Potrebbe anche essere utile consentire a quel livello di fiducia/permesso di gruppo di creare anche tag (create tag allowed groups) a seconda di come è organizzato il tuo sito.
