I simply don't understand why is that you need to lock a thread after 7 or so pages in these forums???????????
WTF?
Beats me.

And I'd imagine that this has been discussed here before.

It is explained here (found in the Forum Rules thread):
http://www.gamesas.com/topic/724862-forum-rules-and-general-information/page__p__10470780#entry10470780

Thats the way things work around here, you'll get use to it.

7 and 200. The magic numbers that are enough for any discussion.

Because 7 is the Number Of The Stoat.

There is already an active thread about this.
