I would PM one of the moderators personally, but I think you’re okay. Many WiP threads get created and eventually die off from lack of activity on the author’s part for one reason or another.
If you don’t feel comfortable with making a WiP thread, then I’d recommend checking out these two threads which might be perfect for you!

@poison_mara’s workshop allows for writers who just want to write but have no interest in getting published. @Autumn19’s thread might be of use to you if you’re new to CSIDE or if you like working with others to set goals for yourself or bounce ideas off of each other.
