a small note and comment on this.
I registered quite a while back, and per the email I got when I did so:
Before you can login and start using the forum, your request will be reviewed and approved. When this happens, you will receive another email from this address.
So I waited....and waited...and finally sent a follow up note, and still nothing. (and yes, I checked spam filters etc.....)
Just today it occurred to me to try the username and password i had registered with, and it worked just fine.
If there is no follow up mail, the message might benefit from being changed to 'if you don't hear....just try it' since some of us are patient enough to just keep waiting...and waiting.
