While many of us are more than happy to help those of you interested in AI, please remember that a lot of us, although in different sororities, are friends here on GC.
In talking to some GC members in e-mails, we have noticed something similar happening. It seems when some PNAMs (not all!) ask us for help and find we can't provide an "instant in" to our GLO, they disappear. This, after we go to great pains to explain the process, and patiently answer all their questions.
Then... after that first PM, we have discovered they go on to the next person in a different GLO, once again hoping for an "instant in." When they find out it isn't that easy at that particular GLO, they go on to yet another person without a followup PM, nor a "thank you for taking the time to answer my questions and share your experiences"... nothing. I was amazed to find out from others that there were more than a few of us on GC who had experienced the same thing.
This is not only bad manners, but it can hurt your chances of getting any more help or advice from anyone here on GC.
If someone takes the time to write you back and help you, even a short PM saying "thank you" will be appreciated and make a good impression.
Having said that, I am still delighted to help PNAMs who are truly sincere about becoming an AI and who are willing to put forth the effort that is needed to find their home.
Good manners go a long way.
