As you seem to be a language purist (which is good ;-) ), you may be interested in this:
'Again, thanks in advance for your time, help, and monetary donations. Oh, wait, not the right place to ask for the LAST. Sorry.'
should be
'Again, thanks in advance for your time, help, and monetary donations. Oh, wait, not the right place to ask for the LATTER. Sorry.'
No pun intended!
Good luck
