[quote]I'm not sure if it's been brought up before, but could a means of inviting new participants to PMs be added? This doesn't seem to be possible currently (though I'm relatively new here, so I may simply be missing something obvious).[/quote]	In addition to interest check threads, marking the RP as "Apply" or "jump-in",or - if you have had contact with them and have the feeling they might be interested -  pinging them in the thread or even PMing them?

[quote]In the same vein, it would also be nice if there was a feature to remove oneself from an ongoing PM thread, as well as for the OP of a PM thread to have the ability to remove participants if needed/desired.[/quote]	Things like that are planned and fairly high up in priority, as far as I know.
