The simplest thing for me to do is get my data formatted (outside of Snitz) in text format, and then post it with the [code] [/code] tags around it to keep the formatting intact.
--Jördan It's a wasted day if you don't spend at least part of it flying upside down.
You could enable html so that people can use tables, but it is not recommended to do that (opens up security risks). Others have created code that would allow you to make tables. Do a search in the MOD forums, ASP forum, and Community Discussion forums to see how others have done it.
As said in that topic, it's not fool proof as your members could mess up your forums by leaving out some of the tags, but at least it's safer than when you allow HTML (a lot more damaging things can be done then).
