Just thinking, if someone spends enough time on this forum to achieve a "Senior Member" status, I would think it be appropriate to send them a cool AR-15.com T-shirt. Of course, a few moderators would need to double-check to make sure that the new Sr. Member is actually posting worthwhile replies and topics (in other words, not just a bunch of stupid "Yeah I agree" posts).
Why would this be good for AR-15.com? While not only adding a bit more pride and loyalty to the member, they will be advertising this site to others when they are at the range or wherever they wear the T-Shirt. THEN, that would increase traffic to this site which is of course the all-important measurement for how much you charge advertisers per month.
A side benefit is that if the AR-15.com members wear their T-shirt to any gun related event (match, gun show, etc.)...they will be able to meet some of the members in person!
Just a thought...
