Filtered to Ron, Rose W, and Tonks
I was talking to Sam Winchester about his ideas for a security alert, something to keep people notified when we're in an excessive amount of danger (more than usual for around here, you know). I mentioned the coins we used to use for the DA, I don't know if Tonks or Rose know about them, but they were a brilliant idea of Hermione's where she could send a message through them and they'd grow warm to the touch if we needed to see them.
I thought since they're small and discreet and easy to carry that they might be useful here for this. I have the basic idea behind the spell but I'm not sure if I've got it down and it would take a while to equip everyone here with them even if I do get it.
If any of you want to lend a hand and test to see if they'll work properly and then, if we can get them to work, help me enchant a bunch of them, that'd be brill. OH also, if you've got a better idea than coins, that would be great, too.
