Well, as example you can take a look on my own wiki website. Because it is all in italian, I'll give you just few hints: the wiki contains some house rules for a fantasy Role Playing Game. Thus we need to show how each spell works. The first category (in italian Categoria) is "Spells" (in italian "Magie"). http://www.usnb.it/wiki/index.php?title=Categoria:Magie As you can see there are several Subcategories (in italian Sottocategorie) grouping several kind of spells and just one Article containing a DPL extension based page with a list of all the available spells ("Riepilogo delle Magie") Thus, the tree is as follows Category:Magie | +-- Category:Magie Elfiche | + Articles | +-- Category:Magie Druidiche | + Articles | +-- Articles | // Thus, you can use the same approach for your problem, moreover you can give each articles a double category (I don't like it very much), say both "String Functions" and "VB:String Functions" Best regards G. -- Giuseppe Briotti g.briotti(a)mclink.it "Alme Sol, curru nitido diem qui promis et celas aliusque et idem nasceris, possis nihil urbe Roma visere maius."
