For a link to display one word but link to another you would need to do this: [[Article name|Name of link]] - which produces something like the following example: the Inquisitor. To use your example, you would type [[Classes|Class]] to get Class. If this wasn't what you meant, let me know and I'll think what the problem may be.

RE:How do I use / set up a redirect page?
Firstly, i'm sorry I forgot to get back to you with the first problem; if its still occurring let me know and I'll do my best to help. As for setting up a redirect, its deadly easy - simply create a new article under the desired title and insert only the following content: #REDIRECT [] along with the desired destination and that's your redirect. For example, if you wanted to redirect Imperial to Sith Empire you would insert only: #REDIRECT [[Sith Empire]] into your 'Imperial' page. Alexsau1991 (talk page) 20px 20:39, August 31, 2011 (UTC)
