Hi there!
I'm not to far away from you (Western Branch of Chesapeake)
I had the same thing happen to one of my African violets in the past and now I have another with a long neck. I planted it deeper in the pot and it did fine - but think I should have trimmed some off the bottom according to the experts at the African Violet Society of America - now I need to do it again.
They have an excellent website - here's a great link for care African violets - the faq's section covers many areas of care for these
plants.
http://www.avsa.org/Faq.asp Your AV's look pretty terrific!
Turning those AV's so they have even light distribution helps keep em
growing straight (I forget a lot myself) but they let me know in a hurry.
Your neighbor,
Sharon
