I use
http://rolz.org/group# for my online game. You can create a chatroom that everyone can hang out in to see the rolls, and there's also a log as well.
The reason I like it, is because of the dice codes. There is a command for counting Hits, and also a command for counting Hits, and rerolling 6's to see if more Hits are rolled.
Example, to roll 10d6 just counting for 5's and 6's, you would type 10d6e5 the result is listed like this
10D6E5 => 4 | ones: 1
But you can click the result, in this case the 4, to expand it to see the actual rolls.
10D6E5 => [ 5; 3; 2; 5; 6; 1; 2; 6; 3; 3; => 4 success(es) against 5 ] = 4 | ones: 1
To roll with Edge, where it counts 6's, rerolls them and checks for Hits or more 6's, the command would be 10d6m5
10D6M5 => 8 | ones: 2
10D6M5 => [ 6 4; 2; 6; 6; 6; 3; 1; 5; 5; 3; 5; 6; 2; 1 => 8 success(es) against 5 ] = 8 | ones: 2
So, this is what I use. Just create a unique chatroom, so you don't have others using it while you aren't there and ruining your logs
