Hii,
this is my frst contribution here,,, and its actually a question for users who are familiar with software

1- How to add a variable to email .. like {city} or {Location}
i have the entry ready and setup,, but in emails i still get dear user at {Location} instead of dear user at LosAngles

2- is there any way to make subdomains works on home page instead of categories,,
for example, city.domain.com/listing/books works fine
but
city.domain.com would return undefined page

thanks in advance for replies
