I have been looking for some good conferences to attend and recommend to colleagues. Looking up on Google and some sites, I thought it would be a good idea to create a list of SQA conferences, the place and the time of the year they are organized with the feedback from the individuals.
The format that I was thinking of is to have an answer for each conference, and people can +1 if they recommend the conference and post comments on why they think so or if they feel otherwise.
For now I will just list some in my answer, and based on the feedback one of us can convert to an answer for each.
P.S.: If you just want to check out a list of conferences, here's a good link: http://www.getzephyr.com/resources/qa_conferences.php
