Two wording errors.
I'd just like to point out two errors in wording that I've been seeing quite a lot recently.
Firstly, validation. This was already brought up by hourglasshere. When saying about email filters don't put "temporarily alter or disable", instead put "temporarily disable or alter". The difference is a subtle but important one. I'd also recommend looking back at other blurty_hs posts for other suggestions on wording and how to answer various questions.
The second one is something that rat pointed out to me the other day. modify.bml does not have a little box at the bottom for people to put in their overrides. Instead it has a button saying proceed, and this leads to a page with said box at the bottom. Please be more clear in your instructions if explaining how to use overrides.
