Question about Spark

I work for a small company sized between 4-25 employees, I have Openfire server & Spark client is there any restrictions that can be coded as a plugin were only a manager can send a message to the employees, either by individual messages, or a broad cast message.

We dont want the employees using this as some sort of AIM/MSN type of messenger except between each other.

If this has already been discussed I apologize as I am looking for a pretty fast answer.

I think you can achieve that with Packet Filter plugin. Though i didnt quite understand this comparing to AIM/MSN. Your users won’t be able to talk to external networks, unless you install IM Gateway plugin.

Yep I read the plugins and saw Packet Filter was my best bet this program rocks !
