Africa should have one... It probably won't be the most active, but it seems fair as its an entire continent, and tennis is growing (slowly) there.
It's indeed elitist and racist of Tennisforum to allow "Latin America" and "Asia" and Ociania ("Aus-NZ") but refuse to create "Africa" section. In fact the section "rest of the world" is a misnomer because it basically refers to Africa and the small European states that don't have a separate section.
So in fact there might as well not be a new Africa section but the "rest of the world" renamed into "Africa" and the tiny few remaining forum-less small European countries moved out of there and distributed to their neighbors who already have separate sections (for example Ireland should be added to the UK section, Luxembourg added to the Belgium section, Cyprus and Macedonia to the Greek section (or if the Greek start bitching and moaning about 'there is only one Macedonia' then open a separate "Balkan" section and throw the lot there with the Albanians and so forth...
