The BOB script, which I have used for a long time now, is a poor replacement for true replay support. In my opinion, the goals of this project should be:
1) Allow a player to see the board at the start of any past turn (not just between rounds) with whatever board visibility the player had at that time. Imagine giving the player as much information as if he had checked the game before every single player's turn and taken a picture of the board. This more closely mimics a real board game played in person, while still supporting fog. Outside of freestyle games, there should be no advantage on a turn-based game site for the player who checks his games all the time to get extra BOB snapshots. Other turn-based game sites support exactly this feature and there is no reason conquer club should not.
2) Make the feature universally available, not an add-on. Don't give an advantage to players who happen to know about a particular greasemonkey script. Don't force players to run greasemonkey scripts (which should be avoided whenever possible, from a browser performance perspective) just to use a basic replay feature. Don't rely on players remembering to click a snapshot button just to have some replay support.
3) Remove the need for courtesy rules like "at the start of the game, allow 12 hours for the opposing team to grab a snapshot before moving". This rule is used in many tournaments because the BOB script is the default replay support. This situation just leads to friction between players. Sometimes the rule is honored, sometimes not, and sometimes it is assumed even when the tournament didn't suggest it. If true support was available the courtesy rule would be totally unnecessary. The playing field would be level without it.
Anyway, I went looking for this thread again today and was disappointed to see that it has been hijacked by discussion of the BOB script. The BOB script is NOT a good solution.
