There is an option to join a guild you've been invited too. But no option to decline.
When you re-login all invites will be cleared.
Yes, when you log in again, they're gone. However, there are times when I am just spammed with invites. I would like to just decline the invites right then and there. Even better would be an option in the menu section where I could turn off guild invites.
