Google asks if I meant 'duodenum'. I just ignore that since I don't need to learn about the small intestine. It displayed the results for unodenum forum beneath.
Perhaps Nivek can add keyword tags like alien-ufos.com, alienhub etc on the control panel for this forum.
I just did a Google search too (my Google is Australian google.au) and did the same, asked me if I meant duodenum and I also ignored it, but even doing that, the results didn't show anything relating to Unodenum.
The only way it would show Unodenum in the search results was if I refined my Google seach and typed in "Unodenum" with the parenthesis ( " ) on each side of the word, but most people wouldn't know to do that in order to be able to refine their Google search to get specific results.
Then I typed in Unodenum Alien and I got a results for Alien cancers of the duodenum and heap of strange links to do with guts worms and other stuff....
I think it it's harder to be able to get results for Unodenum in countries outside of America (I have my main language options set at Australian English and UK English before USA English so I usually end up with a mix of Australian, British and American links in my search results). Like 22 said, some sort of specific tag words or wording or in the link itself would help especially for those people not in America...
