stupid question!

don't worry it took my 5 days to get that one! i still don't know all of them. i just now know that UGF is, Under Gravel Filter(i think)
 
And this can help other people, too... I am always yattering "LFS-this" and "LFS-that" to my husband (who I guess was actually listening, which is amazing enough)...

Well, he had to go online to find out some info on the new bike we bought our son and they kept talking about "your LBS", so he knew what that meant!
