I registered for it, but never got a confirmation e-mail. It's been like half an hour, and I want to ask a question there. Any suggestions?

Maybe the admin enabled registration moderation so he has to approve registrations himself?

Well, it can take a while. Don't worry about it.

Check your spam folder. If it's not there, try registering again using a different e-mail address. Gmail is an easy one to sign up for and doesn't completely block e-mails that Yahoo and other ones do.

I don't remember, but I think that forum was one of the ones my Yahoo account blocked...

After going into the Spam folder and moving it to the Inbox, Yahoo will no longer block messages from that address. I would try registering with all the same credentials. In case the first registration failed for some reason, the second one will have the credentials you want. If the second one says it's already registered, then you know the first one worked. You'll have to wait it out if it's not in your spam/bulk folder.

Edit @ below: Because it's not directly on topic, I edited instead of replied. You have to enable the Spam protection within the options. Afterward, as you mark items as spam, the system will become more aware of what you like to keep and what you don't. It's still a good idea to quickly browse the spam folder for anything that was improperly marked as such. I've been using Yahoo mail for a very long time and I rarely get a spam message in my inbox.

Actually, there's the odd e-mail here and there that Yahoo blocks completely. I've had the e-mail for about 3 years and it's only blocked 2 e-mails that I know of, but it happened.

The rest of the advice is good though.

Okay thanks. I've been checking my spam folder, and nothing is there that is from a forum. I will try to register again though.

Is there an option to email the board admin?
