Opinion? Invitation for letter from PNM

[lostmama]

Hi, thanks for reading and apologies if this has already been covered. I tried searching but I don't think I'm using search correctly. I was reading an open letter on the recruitment page of a sorority site that my daughter is interested in and was surprised to see "If you wish to send us a letter, we would love to learn more about each of you!" I checked the other sorority sites, and this sorority is the only one with the invitation. So, I'd appreciate an opinion on whether my daughter send in a letter. If so, should it be a brief introduction? Anything specifics? She has 1-2 recs going to the chapter. Recs are due this week. She could write a letter tonight and send tomorrow. I'm concerned that it may seem too late and they may question her interest, or it may seem too over the top? I'm not sure if they have received many letters. Many thanks for your input!
