There are many "actions" you can do by just typing into the url,

like: /action/pm_send/to/admin/subject/Hello

With creating a PM like this what else can you add to the url?

I am using this for some links to send a PM to a specific user with a specific subject

There are similar ones for starting topics. I believe you can also use "message" in the URL to include the start of the message

What about label and submitting?

You can't auto submit things, as in theory you'd not display the ads. Nor can you label them automatically. Any reason you want to do these?

Yes, if you look at my website there is a top nav, clicking on Groups you will see a link called create group, that is part of what I want the labels for

You seem to already have that link do something!

Yeah, it starts a new PM with a specific subject

If I were to tag a conversation, the tag won't carry over to the admin. So there's no way exactly to do this It'd have to tagged manually! =/

That sucks

Sorry!
