Buddypress

I'm running a buddypress website, and we need the following items to be done: 1. When a member "Add friend", button become "-1", instead of "Friendship request sent". Note: Real buttons are in spanish: "Agregar amigo" and "Solicitud enviada" 2. When a member accept friendship request, a warning red message appears saying: "You could accept frindship request at this moment, please try again in a few minutes" But friendship is correctly accepted. Note: Real buttons and message are in spanish: "No has pedido aceptar la solicitud de amistad, por favor intentalo en unos instantes". 3. Fix the members list in hidden groups, they don't show. 4. Create a backend option to "Enable" or "Disable" suscribers for publishing in the index and hidden groups.
