So like, a lot of us use backalleys to update things, and while this is useful, it's be easier for certain things if we simply had the option of having an editable notepad, instead of simply updating and posting something again (not limited to SRs). It would need to show a time for the last time it was changed though, but not full revision history. It could be share-able like a back alley or not. 

I'd say that this might bea good change for the ba threads. But only editable by the originator
