Meaning of 気負わずに奮ってご参加ください

Question

What does 気負わずに奮ってご参加ください mean?
Is it like 気軽にご参加ください?

Context: an event information page announcing pre-requisites for attendance:

前提知識

Javaでのプログラミング経験がある方が分かりやすいかなという程度です。さらにAlfrescoを触ったことがあれば理解しやすいかもという程度です。

気負わずに奮ってご参加ください。

I guess it says Even if you don't fit the pre-requisites, you are very welcome, am I right?

Answer 1

"Pre-requisites: Should be easy to understand for people with Java programming experience. Also may be easy to understand for those who have worked with Alfresco as well. Take it easy and join us."

kiow-a-zu is negative form of the verb kiow- "to get worked up, be excited". furutte is an adverb meaning of one's own volition, positively etc.

Answer 2

I would just translate it to "please do not hesitate to join us" as a free translation (意訳).

奮う
