What's the best method to do this.

We did a raid last night where nothing dropped...so when I upload the grss file it acts like nothing to do...doesn't show up on attendance or anything.

But, I want to give people dkp for attempts...whats the best way to do that?

GRSS has the ability to do manual snapshots. If you attempt a boss but don't complete it then do this /grss <bossname> attempts=x
that will provide a snapshot with everything you need. If you just clearing trash in an instance and not attempting any bosses then I like to do this. /grss zg trash clear start and when we leave /grss zg trash clear end. I look at them and whoever was present for both would get whatever points your going to assign.

You'll need to manually initiate the snapshots for when you want to give points. So for example, after an attempt, you type /grss Vael 1st attempt. then after the next attempt, you can type /grss 2nd Vael Attempt

It will take snapshots at those particular moments then.
