When I clicked on the "donation" page my firefox browser posted a warning about it. This is what I found.
--------------------------------------------------------------
Linkers uses an invalid security certificate.
The certificate expired on 5/20/2012 10:12 PM. The current time is 5/27/2012 12:16 PM.
(Error code: sec_error_expired_certificate)

Looks like someone needs to do an update.
