Likely nothing you can do but why do the semi-colons turn into commas when a PM is sent to multiple recipients?

A "reply all" type button would be great, but otherwise I'm doing cut & paste of the handles in the to field but then need to change the commas to semi-colons for them to be recognized. I also need to remember to add back whoever sent the pm, and remove my handle but that's another story and not your problem.

Obviously not a big issue but figured I'd ask
