Hi Robert,
Want to share Java skills with other professionals? Here I suggest a skill exchange website for you.( http://yirihome.com/)

It's a 1 on 1 knowledge trade. You learn from your skill partner and teach another skill back. We do this everyday at work in a company. Now you can do it with local people.

1 on 1 is better than a group! Enjoy you exchange~

Good day Robert. I just joined the sharepoint business user's group and seem like we have simular backgrounds and interests. I am planning to attend the meeting next week and if you will be attending, lets chat for a bit
