I asked the chapcom to take a quick preliminary look at your bylaws, so that you can have some feedback before you put on the finishing touches. We are generally happy with them as-is, although we do have a problem with point 1.4 under "Statement of Purpose".
Chapters are legally separate and distinct entities from the WMF and each other, and it's a good idea that you not attempt to build close ties with the WMF into your bylaws. It is okay to mention that your aims are similar "to other open-culture groups, such as the Wikimedia Foundation", but you should not include that forming a affiliation with the WMF are part of your aims. You can also mention that your goals include "supporting open-content websites, such as the various wiki projects operated by the Wikimedia Foundation", or something like that.
Please let me know if you have any questions about this, or if you need any other feedback regarding your draft bylaws before you want to submit them to the chapcom for approval.
