I am going to. I tried signing up for that darn Unseen Servant twice and it won't send me the confirmation email so I can start using the system and documenting the rolls.
ALSO! Rules question: If my creature has a triggered action that is met by more than one occurrence, how many times can that triggered action occur in a round?
I can't get Unseen Servant to send me an email either. Very annoying. There's another site I've been using in a different game that seems to work and tracks rolls by character, I'll grab a link in a minute.
Edit: here it is. It's not pretty, but it works.
On triggered actions, if it's an immediate interrupt/reaction, you only get one immediate action per round.
Unfortunately for us, no action means it can be used as ...well...no action, wherever. But I think only once per turn (that is, it affects each person triggering it once)
It has been down for long spells of late, with brief periods of activity. I've had a go with the Unseen Servant in Lilli's last combat post and it seemed to work for simple stuff.
