As far as i know, when Slovak forum starts, there were two threads. One was about NT elections rules and the second was about BB-forums rules.
And i look into the conference rules and there is nothing like:
You can post private league posts only in Private league ad thread. So I thing of two ways how to handle with it.
1. Ad the rule into conference rules
2. Stop prosecuting users for not breaking conference rules.
BTW: ebuestlo, thanks for informating about this. Before I read this, I would also delete this type of thread on BB-Slovakia and Czech. Now, i will let them be:)
