Do you need volunteers?
I too, moderate on other forums and would be happy to have a "delete" button for these clear-cut cases. I DON'T want to police other issues, but as has been pointed out, there's ...

Calc'd weights. Well, mass really, not sure what your local acceleration is.
Bob, Assuming those diameters are exact and the alloy is close to titanium's density of 4.506, then I calculate 4.1, 9.1, and 16.3 grams per 18" rod, respectively. Times 10 for the pac...

Re: Re: "Deodorant in a chapstick tube"
Roger, for a smart guy, you seem to have mixed up the functions of deodorants and antiperspirants. Killing bacteria whose byproducts smell bad is one effect and is different that stopping sweating ...

Re: spam
Agreed. I moderate a much more sensitive forum and have annoted many co-moderators. Everyone does only as much as they are sure of. Deleting such obvious spam is low-hanging fruit. High-functi...
