Hi Rohan (and luv-main),
1/ is the proxy form asking for my address at the first line commencing "of" ? ;
Yeah. That's common for legal forms and such. I think the purpose is to distinguish you from the evil-twin Rohan McLeod from a parallel universe, who lives across the road from you. IANAL, as they say, but if you don't feel comfortable putting your precise address there, then putting your town/suburb, Victoria, would be practically sufficient and observe the rituals.
2/ if for example I was using Lev as my proxy, what should go at the second line commencing "of" ?
Well, one formula we think can properly go in there would be something like of unknown address, currently President of Linux Users of Victoria, Inc. It would clearly distinguish our Lev from all the other Lev Lafayettes in the known universe. -- Smiles, Les.
