I wouldn't call myself a full blown member of this community just yet, however lately I have been spending a good part of my online time lurking here. Hell, even Facebook has taken a back seat!

One thing I've learned on my own is that waiting for your next order to arrive SUCKS! (My Nakhla should be here tomorrow!)
