Unlimited raising is allowed in no-limit games which currently how tables are configured as no-limit. I may need to check for pot-limit and fixed-limit which will have a max number of raise allowed. I'll need to configure pot-limit and fixed-limit tables so that players can go there and play with limit raising.
It's a matter of flavor, some players like to have unlimited raising as for high stake poker, others may opt for pot limit games.
Likewise, Happy New Year to you!
Don't know for Black Jack as I haven't played here but to be able to award a member at runtime , it has to go through the add-on API that XI has here but it only allows trophy award programmatically but not badge but it's the same concept except trophy is bigger reward which requires more than one task to get completed which made up an achievement. A player can for instance, must have played at least 2 hours in overall, has made through level 3 , with a certain required minimum amount of cash and has won few types of hand type at showdown to earn a first trophy.
XI currently does not have trophy configured but only badge so trophy can be used to award an unlocked achievement. It can be done though.
