LOL. Boy can I relate. I wish they had an "I've abused my posting privileges and I need to take this idiotic post back" button.
Recently, not only did I misread a post but my math in the response was completely screwed up. I deserved some kind of demotion and dock in pay. Hopefully, I will not repeat the experience, however, I do know enough to understand that is probably wishful thinking. ; )
FReepers are sharp but most are willing to overlook mistakes especially if you admit errors. However, a few like to collect mistakes because they are the thread nazis..."silliness doesn't belong on the FR" or "this is a duplicate thread (one second after the first was posted and you received 45 worthwhile responses" or "The mods frown on yadda yadda yadda" or "your latin is a misnomer" (grrrrrrrrrrrowl what I'd like to do to them)
