Dan,
Thanks for your reply.
To give an overview.
1.) I have my custom CSModule defined in the CSModule section of communitserver.config file which has some additional key in it like serverAddress="http://abc.com/mywidget"
2.) I have created my Emailextension Class to extend the email content before send email which is all good.
3.) within my Emailextension class I want to access the "serverAddress" defined in the communitserver.config for my custom CSModule.
I hope i explainged my scenario.
So any suggesstion on how i can access it?
