Thank you Ira.

I will incorporate these into the existing document sometime before next Monday and post the document. In the meantime, please review Ira's changes.

There will be no WIMS conference call Wednesday 10 August. I propose a call for noon EDT on Tuesday 16 August. If you have comments on the WIMS protocol document and are not able to participate in a conference call at that time, please email an alternate day and time to the list and we will try to accomodate.

Thanks.

Bill Wagner, Chairman, WIMS
