Hi Thomas

      I have been known to go back through the archives on the rare occassion
Primarily I'm interested in the recordings by others of the large events 
M7++ ones.
there has been times when for what ever reason I didnt get a copy in the email
or a hard drive crash has caused a loss of historical data.

  On that note I was very grateful for Larry's archive as earlier this year 
I realised I
had lost all the SDR files of my own events that I recorded between 1996 
and 2000
in New Zealand prior to coming to Australia.

In general tho, I would suspect that the archives are not looked at too often
by many people. Regardless of whether the archived data is used by 
professionals
or not, is still a great resource and should be continued.

The only real comment I would make about whether to upload files or not is that
maybe people should screen their own files before uploading.  If you cant 
pick out
a reasonable P and S arrival, then in all honesty, its probably not worth 
posting.
Of all the files that come to my mailbox via the list server, many of them are
deleted because of a lack of distinguisable P and S arrivals. Really, its
no good for anything other than wasting hard drive space.
So think about Larry's server before you upload your next file, are you 
uploading
something worth keeping or is it just filling Larry's hard drives up with 
garbage ;)

There are many events I record but dont upload for that very reason :)

OK I have had my soapbox muttering for the week  haha

cheers
Dave
