1. When writing a Megillas Ester, is it proper to follow the opinion of the Rashba not to be mafrid negi'os that happened before both letters had a tzuras haos? I know that the Keses says to be makpid like the Rashba other than tfillin and m'zuzos that you have written past for which one can rely on the Shulchan 'Aruch, but is he including Megillas Ester also? Or perhaps since it is kasher to leien from either way one need not be machmir? 2. When writing a shem kodesh with a prefix, i.e. leilokim, at what point should one say l'shem kdushas HaShem, since the nitfalin l'fanav are not nitfas in the Kdushas HaShem?
