[quote]TTI[/quote]

You sure it's TTI and not TTM? TTM means through the mail. It's when you receive an autograph success through the mail.

In Person, it means you met a celebrity and they signed in front of you.

It's a good idea to send a SASE with your request. You can write whatever you want to write. If you write to people you are a fan of it shouldn't be too hard. Tell them what you like about them. Always be polite and friendly. Try to handwrite your letters and don't make them too long. 1 page is usually sufficient.

I need to ask what some of these abbreviations mean (not just what they stand for).

I also need to know how to contact a celeb to ask for their autograph. Shall I provide a stamped envelope with my address inside the envelope I send to them? What shall I say to them.
