Hi Scott, Because you posted this thread some minutes after i edited my post to OFBIZ-1528, i have to say that in some cases it is better to edit than adding new comment. For example while commenting on OFBIZ-1528, i pressed CTRL + R by mistake and sent the comment not finished. That's why i decided to edit and complete my comment.
Otherwise i agree with you that reading edited comments is more difficult than new ones. +1 for not editing comments, when not necessary. Bilgin
