What's the difference between InDesign User Group (InDesignUserGroup.com) and the Adobe Groups user groups (groups.adobe.com)?
First, InDesign User Groups are intended to hold in-person meetings, whereas Adobe Groups can choose to meet in person or virtually.
Adobe Groups can focus on any product, technology, or combination they prefer, InDesign User Groups are (obviously) InDesign-centric, though they can certainly discuss other applications and workflows.
InDesign User Group chapters are typically created and run in major cities -- locations where there is likely to be sufficient interest and volume of interested users to be able to support and justify the invested resources. Adobe Groups can be formed by and for any number of users in any location.
We believe that keeping InDesign front and center strengthens the groups and helps keep the instruction relevant and the expectations of members met. The InDesign User Groups community attracts a high caliber of presenters, and its ongoing success and growth builds on itself.
