Stories of Tie Up Games

Where do I write my story then how do I attach?I don’t want any proof of me being here

You will need to post the story under your username.
If that doesn't suit you, don't post.

If, however, you do want to post:
1) Write the story and save it somewhere.
2) Decide the category in which your story best fits.
3) Select the category from the Board index.
4) Hit the [New Topic] button near the top.
5) Paste the story.
6) Hit the [submit] button. (Don't forget the gender-tag)

Got banned when I did that last time

Well, you're here now.
I don't expect you were banned for following the instructions above.

Just checked, the ban was for repeatedly posting in the wrong section in spite of warnings.
Should be alright now.
