I'd just be wary of pushing the guild like this as we had an issue several months ago with the server crashing and causing numerous problems for members. Turned out to be a BB code that someone activated, but we weren't really told what it was so that people didn't attempt it.

Multiple hiders could do the same thing if it breaks the page formatting and requires more processing power from the server.

Edit: as it is, this page itself does seem a bit slower than normal to load because of the amount of hidden content.
