It could possibly be in the new member sign up prompt? The same location that someone is creating their username and password. State that forums are just like hunting camps, if you go running into someone elses camp and say " I haven't seen anything in a week! Nor did I scout much, ive got a buck tag are you boys seeing anything?" Your not going to get a very welcome response. I think scottr stated that Eastman's intention was to make hunters better and more knowledgable in the field, a welcome email before being able to post. ex. in an email verification? That touches on the intention of eastmans forum and what the members are all about may be a great introduction to set the mood.
What I am thinking is when you are on the "Forum" page, right under "News and Announcements" have the next section entitled "New Members" within that have section titled something like "Introduce Yourself: If you've just joined Eastman's, introduce yourself to the forum members."
Another thought is when sending new members a confirming email, include a sentence or two encouraging them to introduce themselves in the New Members section.
This sticky could be at the top of that section.
+1 on the golden rule. Trying to give more than you get is also a good guide.
+4 on thanking people, too. I noticed that I had not done that much and am trying to do better. It's like giving compliments - how many times have you been impressed by someone or by what they did but leave it unsaid when a simple compliment that takes a few seconds would make the other person's day?
So, BB let me take a second to say I should have left you about 100 thanks for your posts over the last couple years - always very good and helpful info, and well delivered. Just as one example, which spotting scope I bought last year had a lot to do with your comments.
Now therefore, please take your weapons, your quiver and your bow, and go out to the field and hunt game for me.
