I know nothing of programming, so if this idea would be a programming nightmare, please forgive me.
In the interactive PGN board that can be embedded in forum posts, I think it would be useful to have a feature that let you explore variations within the PGN. When you are playing though the moves and you reach a point where there is a variation, a little box pops up that allows you to enter the variation and play through that rather than the main line.
I've recently started a club where the members work through problems from grandmaster games, and it would be helpful in posting the solutions, rather than just having the text of the variation to look at as to why that particular line is not correct.
Just an idea...
