Delvianna, you aren't banned. If you've been using the java link (provided elsewhere here in this forum), there could be a glitch in your java app, as Medievalist suggests. You might have to remove Java from your computer and reinstall it. Also, you could visit StarChat.net and browse around there for hints to solve connection problems.
But the best and most reliable method for visiting our chat room is to obtain a true IRC client, such as mIRC, PIRCH, IceChat, Chatzilla, or the like. Some are completely free, others charge a small one-time registration fee. I use mIRC and have no problems gaining access to the chat room. You can download StarPIRCH from Starchat.net and that almost guarantees you'll have no trouble entering chat.
