There is absolutely nothing Macil can do, without entirely rewriting the quick reply in php, and I am not even sure if that's possible.
To put it in laymans terms, Opera Mini runs as fast as it does because it's presenting you an interactive snapshop of the website, rather than the actual website, and that's done through server transcoding which I'd rather not get into.
The actual issue is that the data is not preserved by the server, because none of the data is saved. It's just reloaded as a snapshot from the website.
And mlpchan does not have your name and trip as it's default loading state.
There's really nothing we can do.
As you said in this post >>6890
the browser pre-processes the page.
Which destroys your name data in the name field.
Sorry man, you're gonna have to change browsers :c
