Actually, the primary reason is spam. In some situations, IL is correct but yes somebody’s first post could be a link to a map so that you could talk about strategy.
10 posts is either very hard or very easy but I think if you dive in and respond to a few posts in a constructive manner, you’ll find it’s quite easy. One idea is to revive a really old conversation with your ideas on it.
@Imperious:
Because we don’t want spam. Your first post and you want a link usually means you could care less about this site and just want a shout out.
Just post about the game in some meaningful way, sharing your ideas, strategy.
That does not require a link
