Thanks Sherise for your suggestion!
The group is big, diverse and ever-changing, so it is understandable that people want different things.
We will keep the current format (i.e. networking and presentations) since it suits most folks. We will try to keep to the presentation time limits, and try to incorporate panel discussion in future.
The atmosphere is fairly informal, so feel free to skip parts of the presentation if you wish, and of course organize the small group gatherings, like Karel suggested.
