I like banded tournaments a lot, but an occasional big one (in group size) is more than enough besides a lot of small ones. 14 games with just one tournament is a bit too much for a periodical habit, but I know I can stand a handful of games suddenly increasing my game load.
Need to have a start time dead line. I find many of the tournaments sit around for quite a bit before they start. Maybe the functionality would be to have an automatic start time (say 2 weeks from initiation by default - this is a correspondence site after all). That would allow people to manage the pile of new games more effectively.
