It seems that the release of The Pioneer Trail expansion in FrontierVille did bring a good thing, after all: the gift sending limit has been apparently increased to 50 from 40, which means that more people can receive gifts from you and in return, that you could receive gifts from more people:
This might be, however, just a temporary thing as Facebook used in the past to have high limits for gift sending, but the limits were decreased eventually. So take advantage of this little new feature as long as it’s there, it saves you time from multiple gift sending sessions.
Because, yes, there’s still a homestead and people still need stuff for it too!
That’s a Facebook thing. It only lets you send so many at once. You can always go back to that screen after sending to your 50 friends and pick another 50.
