This is a long term feature.

I believe it would be good to have private/public bug notes, and add an entry to the config to specify the threshold to view private bug notes. Or even use the same as the threshold to view private bugs. I believe specifying that for each viewer might be an over kill. I think private bug notes are very useful for internal details about the fix and stuff like that.

OK, it sounds good. It will do.

vboctor told me to add ideas(I)/questions (Q) concerning "private bugnotes" to this item, so I do:
Q: What are the definition/volume of a private bugnote?
I: Addition of an private bugnote must not notify users, who can not see it.
I: Please add a configuration item, to determine which level is necessary to see private bugnotes, default could be "developer".

Both of those definitions are already planned...

Basic private bugnote functionalitity has been committed to CVS, including the configuration item.

Issues with mail and such will be fixed later. Leaving this bug unresolved until then.

I think the issues with mail have been resolved while I wasn't looking.
