Forums mIRC Help mIRC chat cannot post to an active channel problem

I am using mIRC on an active channel and can read all the posting by members but when I tried to post my own message to that same channel I received the mIRC generated message that "#xxxx Cannot send to channel (+m)". However, at the same time, I have also accessed a different #yyyy channel within the same server and had no problem posting or sending my messages to this channel. Can anyone suggest what I can do to correct this issue of not being able to post my chats on the #xxxx channel?

It's telling you that the channel mode m is set (moderated) and only users that are voiced (v) or opped (o) can send a message to the channel. The other channel obviously is not moderated (m).
