When you want to have consistent talks you should be up to date and have someone who can explain something. For that it is of help that some publishers and companies have sponsoring programms for usergroups in place.
Here we want to list some, what they provide and where you can register. If you get books or other written material by them, you should be so kind and write a review when you liked the thing they send you. That way you encourage them to continue supporting you. The reviews you can post on your usergroup page or on your blog.
