I propose that $_SESSION['error'] be removed and changed to $error instead. This means that eoCMS stores less data within sessions and this session has been causing a few problems like the error keeps displaying until you visit another page. By changing it to $error, we can use $error[] (an array) and be able to output multiple error messages at the same time 

Also, the visibility, currently, you cant use a query to get only the data the user can see, you have to do a while() and check the visibility against it and not output it if it does not match. I spoke about this with Paul and we had the idea of changing the way the ranks for boards etc are stored. Instead of 1, 2, 3, 4 (Guest, Member, Global Moderator, Admin) change it to |1|2|3|4|. This way we can use a LIKE within the query

Comments?

I like the first idea about the errors.  This should make error displaying a lot easier as we can then log errors and choose which to display based on rules and such.

As for the second part it sounds like a good idea as well.  We just have to be careful with using like in a query as it can slow the query down a bit. Not that much but it will a little bit.

Why cant use like this :?

Talking about errors the CMS sets, not PHP errors Example: "Username/Password do not match"

I think both ideas are good. If it makes it a lot easier to do but a bit slower then it's probably worth it.
