Where to put this wiki...

Students are working in groups to produce a page of evaluated links to resources around a certain topic in healthcare. Where do I put the wiki?
In their own VLE module? Sadly, this limits the audience and thus the students' awareness of that audience.
In their programme-level VLE module where all students on their programme can access it? As this task is run twice a year, it's soon going to get hard to navigate and muggins is going to have to maintain it. At least building one per cohort keeps it manageable with no overhead of maintaining it.
Somewhere all of our students can see it? This would mean farming them out to a different wiki-space not normally associated with learning and teaching.... politically sensitive! Plus the need to do all the 'gardening' implied in '2' above.
Sigh - looks like I stay with option one. It's, as ever, a trade-off between wanting to do the right thing educationally and yet keep it manageable...
