DW question

[threecee]

I know I can delete comment replies when the comment is on someone else's site, but I'm not sure what to do when someone comments on my site. If I delete it in the Inbox, does it remain attached to my journal entry? I don't want to remove comments on the journal or make DW think I'm regularly deleting someone's comments because they are offensive. On the other hand I would like to keep my inbox uncluttered.
