Also, as the vassal scene is growing (yay!), so does apparently the risk of someone trying to troll or ruin your game.
Yesterday there were several games running at the same time and I noticed them all being locked one after another and I presume that it might have been because the others were experiencing the same as me and my opponent did. A would-be-fool entered our game room and within seconds started flooding the chat with comments, then he started triggering all the different sounds from cards and figures at the same time, moving around stuff in the play area and finally he flooded the dice window with die rolls while we were in the middle of resolving an attack. All this happened in the span of three or four minutes and was clearly intending to disrupt the enjoyment of our game (as well as that of our spectators following it). Having already asked him to quit it, I was eventually forced to lock the room and kick him (which only made the harrashment continue in private tells to both me and my opponent) and proceed to put him on ignore as well. This guy is a familiar name on this forum and no stranger to vassal, so it clearly wasn't the case of someone new to the vassal module and not knowing what they were doing.
So, if you are playing a game and someone is obstructing it, the player who opened the room can right-click on the name of the room in the list of active games and lock it. Once locked you will be able to kick out the person.
And, if you are a spectator, please don't interrupt the game. Don't touch anything - and keep comments to a minimum, unless the players are asking for your input on something.
Also, please recognize that it's extremely easy to change your screenname on Vassal, and so this troll whom you encountered last night might not actually be the person he was claiming to be.
I'm glad that Vassal has the Kick function, because occasionally these kind of people show up and need to be dealt with. Thankfully there is also an Invite function, whereby you can have someone from outside a locked room, join your room.
