Without any doubt, a lot of new members have been posting external links within their posts in the forum section.
In most cases, these new members are unaware of the Forum Rules. They have not read them simply because these Rules are located way back down in the list, which most members, new or old, hardly ever scroll down to. The few top sections and topics are the most frequented by all.
So, it only makes sense that all new members should see this Forum Rules FIRST, before attempting to make any posts. Hence, no more excuses of not knowing the rules! Hehehe.
