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