I'm not really into using this forum for self promotion, but considering how many people seem to have a challenge signing up for an account properly, I'm just going to point out:
a) I use a spam blocker to limit logins, and starting last year it got a lot less effective. I get a ton of signups and unless I can correlate the user name easily to some existing online identity that seems at least marginally music related, I will ignore it.
b) There is a special forum area right on the front page that says:
Trouble registering or logging in?EVERYONE: Post a message here to let me know you're trying to register. I may delete new users if I haven't heard from you first somehow. Do your username and e-mail look like random gibberish? Are you from yandex.ru? Your application, if it is legitimate, may be delayed unless you post a message to reassure me. Too many spam bots! If it's been more than a year since you signed up and you've never logged on, again I may delete your account.
I really mean it!c) The link to the Holy City Audio forum (where you can download SpinCAD Designer and ask questions if you need to) is:
