question for you all!

[vivaciousend]

hi! i'm Jinna and i'm new to the community.

anyway, i have a question.

i have this great idea for a fanfic.
but the thing is... i want me (well, not me exactly) to be in it!

is this wrong? should i not venture into Mary Sue territory? or should i carry on and write to my heart's content?

thanks in advance!
