ok, here's wat happened. i tried to search for my posts.
so in the search engine, i typed my username into the textbox on the right
guess wat...the results were nothing!
i can't believe it...but after a few minutes of tinkering, i realise that the "Exact Name" checkbox was checked
ok, i tried again...so now there are results, but i typed my username exactly as it is, why isn't it working with the "Exact Name" checked?
