Well, I'm happy to say that I'm allowing guest posting for my forum FOR NOW. I really encourage you to sign up, as guest posting could be gone soon. Also, a new shout box, which also allows guest posting. I hope this greatly improves RTH, and there is more to come in the future.
I would strongly disagree with allowing guest posts as this could results to a lot of spam if you have done a bit of SEO.
The shout box is also a negative thing to put on your forums because your stopping your members from posting on your forums as well.
I would also suggest you do some more SEO like "Guest Posting" for example as that will rank your site nicely, make sure you get to know the high ranking blog owner and see if he would allow you to post articles for his niche that relates to your niche. Then ask the owner to see if you can post links back to an article on your forums that is related to the blog owner website that is useful for him and his/her members.

Yes, I had thought about spam, but if that gets to be outrageous (it's still a small forum, for now) a simple click and deletion should solve it for now. And, yea, I think I'm gonna remove that shout out box, as it has just become clutter now. Also, thanks for the SEO tips! I really appreciate the feedback!😀
