AW: status information

Greg,

I'm an outsider to the Subversion development community so you may be surprised by me jumping into this discussion. But as you were shouting to the public you should expect this.

I'm shocked about the tone of your post and I don't see how calling someone "whining" can help resolve technical misunderstandings.

Sorry for staining this thread with my emotional rant but there are two issues you should be aware of:

- all posts to dev_at_subversion are readable by the interested public and affect the reputation of the Subversion developer community as it is recognized by outsiders,

- it takes quite some (emotional) effort for the attacked person to recover and come back to the professional level, effort that you drew away from work on the subject.

Thomas
