Yes, this suggestion on grouping from Robyn works well.
Another similar approach is where you want to offer students several different topics to work on: say, you are teaching "great people from history", you want to have four different people that students can work on (they each choose one). You could start with an optional activity with 4 Share Resources - each named according to the relevant great person. After this, you could have another optional activity, this time with 4 Forums - again named for the relevant great person, and so on for subsequent tasks.
In this way, you can run parallel streams on different topics within a single LAMS sequence. It's might sound a little cumbersome, but students adapt to it remarkably easily once they first understand how you've structured the sequence.
In future versions of LAMS (after the V1.1 release), we plan to provide much more powerful functions for multiple pathways, branching, etc - but this is some way off (probably second half of 2006, based on current development).
