Ubuntu membership can be gained from the Ubuntu Membership board in general, and IF you have sufficient forum activity you can do so via here. You'll understand I trust that you don't fulfill that expectation with 2 posts on the forum.

Read the following details regarding Ubuntu membership.
I suggest you read the general wiki for membership - https://wiki.ubuntu.com/Membership/NewMember
Please do not PM me about Registration issues without having been asked to. I will tell you to post here
