Talk:Home biogas system (Philippine BioDigesters)
 Categorization weirdness!
For some reason, the page associated with this "talk" is not appearing in all the expected categories. Look in Category:Ported content, and you will find a link to a version of the page by an older name, lacking the tag "(original)" in the name. The page does appear correctly in other categories.
