Forums Connection Issues z:lined

Hello, I was chatting earlier left for dinner and when I came back is says I was z:lined. I am not sure what this is or why I cannot get back in, can someone help me or give me advice? Thank you.

It means you are banned for some reason. Usually the message tells you why and where to go for help. If it doesn't, then use Google to find the website for the network you're using and then look for some kind of e-mail contact information and ask them. Bans (zlines, glines, etc) are nothing to do with mIRC and we cannot help to get them removed.
