It seems that while I was actively working at jccAbacus Web, Google changed its policy on Google Sites, now considered more as a tool for working in group than as a creator of web portals. The fact is that months go by and jccAbacus Web remains without being indexed by Google Search Engine and I'm afraid it never will be. It seems that I simply put the contents in the wrong place, or at the wrong time, and that I should consider moving them to another place.
