I thought about adding the number of queries that each option will generate, but ended up deciding just to list them in the readme & here in the post. I may add that to future versions though.
As far as adding more custom templates, there's really not much of a point... The code from the custom templates can easily be copied and added into the index template. If someone
really needed options to turn them on/off, then the settings could be added, and a conditional thrown around the code in the index template. The only reason the 2 custom templates are still there now is for people that have one or two blocks where the content might change often. The info being in seperate templates obviously makes it a little easier to find and modify the content quickly.
Xanthine - The error you are getting is probably caused by entering the path to your forums incorrectly. Can you post the entire chdir line here?
