Blog B contains a few posts in the 'b2evolution Tips' category.
All these entries are designed to help you so, as EdB would say: "read them all before you start hacking away!" 
If you wish, you can delete these posts one by one after you have read them. You could also change their status to 'deprecated' in order to visually keep track of what you have already read.
