Hi Guys,
Think this over a bit. We get MANY newbies that don't know how, or don't want to register on their first post. We'll lose those newbies that aren't able to make their first post.
If we make the forum members only, about half of the spammers will register to post their spam anyway and then there's another chore to remove their registered screenames.
It's up to you, as this is a democratic community, but my vote is to leave it open for guests to post.
I read every post, so the spam does get removed. Occasionally when I actually go back to my life for a while, a spam post can hang around for a couple hours, up to a 1/2/day sometimes.
If the spam bothers you, DONT click on it....
