 Dear Gaussian users:
 Is there a way to loosen the optimization convergence criteria
 in gaussian 92? I found OPT=TIGHT and OPT=VERYTIGHT to tighten
 the criteria but I coundn't find the other way.
 One of my SCRF jobs is running for weeks like below.
 Should I just kill this and run a frequency job?
