For general game issues use the [email protected] and other general addresses.
Use individual admin emails if it is an issue that admin specializes in - or if they have specifically asked you to email them.
For example:
I handle aspects of Trinald that appear to be broken. Post in the bugs forum or send an email to [email protected]
Jane handles link page issues. PM her or send an email to [email protected]
This allows us to respond more quickly to requests and concerns.
