Yeah site searching is fine. To put any limitations on that would just make life hard for players.
Do try to be reasonable tho - it is not acceptable for a player to "just happen" to have a 5 air mage ready to cast wrathfull skies or something "searching for sites" along the border of a warzone
Yes we are playing with v2.15, the latest.
BTW, everyone, msew was the Last player in, the game has now begun!
