To be an equal opportunity offender, geeker 33 and swarb 10 & 17 also have indirect anagrams.
And while I am on my pedantic high horse, I might as well piss off a few more people; Having spent 30+ years as a finance professor, I feel it's important to differentiate between Ponzi schemes and pyramid schemes, and to advise people to not get involved in either of them (either as scammer or scammee):
buddy, while I knowingly posted an indirect anagram, my post #2 was careful to not apply the "Ponzi" epithet to a pyramid scheme. I worked on Wall St. for a long time.
I'm not annoyed at the indirect anagram thing. I occasionally see them (at least as components of a longer solution) in dailies and don't have a big objection. The voters can decide on merit or lack thereof. As far as "fair", I view it as a game: I don't invest overly much time on a given puzzle, and sometimes the setter wins.
Thanks Geeker, and Spike - can see ‘em now. That first one takes me back almost 50 years to first year Uni - something deep in the back of my mind about ramps (hence the oblique clue) being used as part of the construction methodology.
