> I will gladly send the relevant information through the personal message system on the site
If the information is in the form of a document (doc, pdf, etc.) that won't help; the personal message system is only a portal to an email client, after all...
But feel free to send me details if you can; I have Reynaud's syndrome, and don't care too much about who knows it (he says, posting details once again on a public forum)...
> As for the statement "The confidentiality of emails cannot be guaranteed"... it's a statement that is required by my university's institutional review board for things like this
And it's a perfectly sound warning to make; email goes via all sorts of routes and isn't secure, and prone to interception at one of any number of places on its route. Some people might not be aware of this, so it's only ethical to warn them.
