recs

If you absolutely cannot get rec letters for whatever reason (you're a first gen, you don't know anyone, etc.) try the following:

-Sorority Sugar on Tumblr has a Rec Letter connection page
-Sorority Connection on Facebook is full of alumnae that are willing to write rec letters if you tell them about yourself.

Of course, it's always preferable to ask someone who knows you well instead of someone random on the internet, but if you're desperately seeking recs, these are good last resorts.
