I like it, nice job!

Users without avatar don't show up properly though.

WOW, i thought at first....okkkk whats broke...hehe Then i read this.. :) nice job and i do have to say it looks better now, more proffesional :)

Looks good, Stefan! ;)

maybe make the checkboxes disabled so users cant uncheck them;)

Yep looks good, was going to say maybe grey the boxes out to everyone but the coder of the hack.

Looks nice though.

You can't edit it from that page anyways, so what good would keeping it enabled for the coder do? :p

i love the way its set...
this is especially good for those that dont like reading first posts and now people can post new updates to the firstpost and people will notice better and easier

Excellent work: such a useful modification, and so well implemented... I (FWIW) have only two suggestions:I think perhaps have the checkboxes type="hidden", but have images change on the fly with the DOM based on the settings of the checkboxes?

Secondly, the "minimise" setting for the hack info at the top of each thread should retain the user's open/closed setting on a per thread basis: works for forums on forumhome, should be extendable to the hackthreads ;)

Other than that, awesome: *thumbs like way up dood*

Why not just use if conditions in that case?

Either way, I would say disabled checkboxes (or hell, enabled is still fine) is the way to go.
