Yeah, the locking behavior is not something I can easily change at this stage. As far as spoiler code goes, I'd like that also. The link you posted is for an older version of SMF, though, which we can't easily use. Right now we're pretty much waiting on SMF 2.0 to hit RTM, and then a huge new update to the forum has been brewing for a while and will then come out. They do take their time, though, with that.
