I attempted to register for the Wiki <https://svn.mpi-forum.org/trac/mpi-forum-web/register> but failed at least four times. Because no error messages are given, I cannot determine if I am a machine because I cannot read the CAPTCHAs, if my username/password/email are invalid, or if there is a server-side problem. Any suggestions? Even if my failure is not due to CAPTCHAs, I have a great deal of trouble reading the ones that show up.
