If you change your email address, you will have to again register on your site. When you receive the account activiation email at the new email address, it will have an error in it which will not allow you to activate the account. Here's how to fix it.
The web link will look something like this:
Code:
http://www.yoursite.com/modules.php?name=Forums&file=profile?mode=activate&u=3&act_key=bf7df0
Here's what you will need to change:
Code:
change the "?" in /modules.php?name to "&"
For some reason, I haven't figured out yet, the "?" is being inserted instead of the & sign. Make this change, copy and paste the entire link into your web browser and you will be off and running.
