Oh sure. Five minutes is great for those of us that type fast, are fluent in how the forums work, and have broadband. Like you said though, there are times when it is critical to be able to edit and it shouldn't be just those people who benefit. Ever tried to edit and gotten sever busy screens for more than 5 minutes? I have!

On a site like this where security and safety are involved I think its okay to make a few allowances... aside from the fact that it really just isn't that big of a deal
