Just a reminder: if you try and register for the forum with an email address that is potentially fake (e.g gmail, yahoo etc) *and* a google search of that address shows no sensible postings from that address about IC design, your registration will be rejected.
If you really want to register with some fake email address, you'll need to email the glade support email address with a request. This is just to deter spammers, so please don't take it personally.
