Before using aliases it is important to understand how DDO's chat system works. If you have the general chat tab selected then everything you type is sent to General chat (unless it's routed to party chat with /p, or guild chat with /g, etc...). This is because the general tab's outgoing text type is set to General. You can see this by right clicking the general tab and pointing to Set Outgoing Text Type (sometimes the menu doesn't want to disappear. if this happens click Rename twice). If your aliases ONLY contain text then any chat tab is fine when using aliases. However, if your alias contains a '/' then it will not be interpreted correctly unless your current chat tab's outgoing text type is Say. Let me repeat that... If your alias uses a slash, it MUST be used in a tab who's outgoing text type is Say. You can modify one of your current windows to achieve this, or just make a new one.
