Other published authors have mentioned that they are published and put links to their books in their A/A thread.
If you have a website/blog that you are using to promote yourself, you can put a link to that in your signature IF YOU link back to Elliquiy. For example, look at my signature here, and you'll see a link to my website--it changes depending on what my most current blog post is. I have a page on my site devoted to where you can find my work. And, I have at least two links to Elliquiy on my site.
If you are publishing under your legal name vs. the user name you use here on Elliquiy, you might consider that before linking if the nature of the work would be at odds with the adult nature of content here. For example, I also write under my legal name, but that work is young adult fiction and mainstream fiction--(Not published yet!) and that blog doesn't link to Elliquiy.
