- Proper handling and linking of multi-paper presentations/symposia (ie. as in OCS 1.x) including how they are displayed both in the conference schedule and the presentations page. (see viewtopic.php?f=3&t=4835#p20363)
- Allow multiple payment methods (see viewtopic.php?f=3&t=2478#p10547)
- Allow users to see their registration/provide a receipt (see viewtopic.php?f=13&t=5941)
- More flexibility in scheduler (see viewtopic.php?f=3&t=6110)
- Show and group by presentation type on presentations and schedule pages (see viewtopic.php?f=3&t=4835#p20363)
- Allow sponsor logos to be uploaded and optionally display sponsors on front page. (see http://www.imrf.info/2008/)
- Use currency symbols instead of abbreviations (see viewtopic.php?f=14&t=5807)
