I'm starting to wonder if I'm sending this to the correct list. It's been
another two weeks since my last email and I still have yet to receive a
response. In fact, I haven't heard a thing from anyone since I sent the
first patch out (as requested) back on August 10th.
Could somebody (anybody) please email me a response when you get this? If
you could tell me what I need to do and/or who I need to send this to in
order to illicit an answer, I would be extremely grateful for your advice!
I would be even more grateful (for whatever that's worth) if you have any
thoughts on the latest date patch I sent.
Thanks!
