I'm with Monrose. If your a good writer, then of course but if not, post it anyway because it will give toi experience and it will improve your écriture skills. Make sure it's interesting and enjoyable to read. Good luck!!
I agee with Monrose,well it doesnt really matter how old toi are because your écriture skills doesnt Vary on your age but if toi have some form of talent sure why not
