I'm not sure what to say here. A lot of it mirrors what Shane already said. Apologies and sorrow is nice, but that's just talk. Proper amends need to be made. Rigorously honest amends at that.

I can accept that you were angry and you retaliated. I can even understand, to a point.

How you make amends is up to you.

How you behave on this particular site is up to you.

In the end, it's nice to have you back.
