I suggest using the dev version of agreservations, because the beta(yes it was released too early,i am sorry for that) version contains a problem which can occur when the db_sql_rewrite function is called. This error is fixed in the current dev version. A new beta will be released when i come back from the Wacken Open Air festival. I know i am behind my own set schedule but the good news is: its only a few weeks that i am behind shedule and i will have more time for this project from september(double the time!! :-)) + there will be more man (woman) power working on this. So don't worry, we will get it done, it already is an obsession which i can not stop.
